Answer:
length = (3*width) -2
length + 2 = 3*width
width = (length +2) / 3
2*length + 2*width = 68
OR: 2*length = 68 -2*width
If length = (3*width) -2 then
2*length = 6 * width -4
therefore,
6 width -4 = 68 -2 width
8 width = 72
width = 9
Since 2 length + 2 width = 68
then 2 length = 68 -2 width
2 length = 68 -18
length = 25

Step-by-step explanation:
✦ First change the improper fractions to decimals:
✧ ⁵⁄₄ = 1.25
✧ -⁹⁄₅ = -1.8
✦ Then divide:
✧ 1.25 ÷ -1.8 = -0.69
So x would be -0.69 in decimal form.

Evaluate g(x) = 4 - 3x when x = -3, 0, and 5
The values of the given function when x = -3, 0, and 5 are 13, 4, and -11 respectively
From the question,
The given function is g(x) = 4 - 3x
We are to evaluate the function for the given values of x
For when x = -3put the value x = -3 into the function
That is,
g(x) = 4 - 3x becomes
g(-3) = 4 - 3(-3)
g(-3) = 4 + 9
g(-3) = 13
For when x = 0,Put the value x = 0 into the function
That is,
g(x) = 4 - 3x becomes
g(0) = 4 - 3(0)
g(0) = 4 - 0
g(0) = 4
For when x = 5,Put the value x = 5 into the function
That is,
g(x) = 4 - 3x becomes
g(5) = 4 - 3(5)
g(5) = 4 - 15
g(5) = -11
Hence, the values of the given function when x = -3, 0, and 5 are 13, 4, and -11 respectively

Susan will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $70 and costs an additional $0.40 per mile driven. The second plan has no initial fee but costs $0.60 per mile driven. How many miles would Susan need to drive for the two plans to cost the same?
Answer:
350 miles
Step-by-step explanation:
Let x represent the miles driven
The cost with the first plan will be represented by 0.40x + 70
The second plan will be represented by 0.60x
Set these 2 expressions equal to each other and solve for x:
0.40x + 70 = 0.60x
70 = 0.20x
350 = x
So, Susan will have to drive 350 miles for the cost to be the same

Which statement is true Every real number is an integer Every integer is a counting number Every integer is a rational number Every terminating decimal number is an irrational number
Answer:
C. Every integer is a rational number
Step-by-step explanation:
Integers are whole numbers which could be positive or negative and zero. Examples of integers are 330, 21, 10,052, 0, -425, -879, etc. Fractions are not integers. Rational numbers are numbers that are expressed as the ratio of two integers. So numbers that have integers as their numerators and denominators can be rightly said to be rational numbers. Examples are, 5/7, 10,111/880, -365/15.
Since both the numerators and denominators are whole numbers, the entire figures can be said to be rational numbers. So, fractions are rational numbers.
If x2 + ax + b = (x – 9)(x + 9), what is the value of
ab?
A) -81
B)
0
C)
81
D) 1458
Step-by-step explanation:
X2+ax+b=(x-9)(x+9)
X2+ax+b=x2-9x+9x-81
X2+ax+b=x2-81
therefore,a=0,b=(-81)
Then , ab = 0×-81 = 0
Answer:
B) 0Step-by-step explanation:
x² + ax + b = (x – 9)(x + 9)
x² + ax + b = x² – 9x + 9x – 81
x² + ax + b = x² + 0x – 81
x²=x² +ax = +0x +b = -81
a = 0 b = -81
ab = 0(-81) = 0

Answer:
2c + 15 = 25
Step-by-step explanation:
The total he wants to earn is $25, so we know the equation must be an expression that equals 25.
____ = 25
He earns a fixed $15. He also earns $2 per customer.
The total he earns is the sum of the fixed amount ($15) and the amount he earns per customer. Let the number of customers be c. The amount he earns from the number of customers is 2c.
fixed amount + amount per customer = 25
15 + 2c = 25
2c + 15 = 25
Answer: 2c + 15 = 25

What is the volume of the triangular prism?
3.2 cm
6 cm
5.4 cm
A. 8.64 cm
B. 17.28 cm3
C. 51.84 cm
D 103.68 cm
Answer:
C. 51.84 cm³
Step-by-step explanation:
Volume of traingular prism = Base Area * height of prism
Base Area = ½*base(b)*height(h)
Where, b = base of traingular base = 5.4 cm
h = height of triangular base = 3.2 cm
Base Area = ½*5.4*3.2 = 8.64 cm²
Height of prism is given as 6 cm
Therefore, volume of triangular prism =
8.64*6 = 51.84 cm³
Volume is C. 51.84 cm³

Solve the literal equation −cy+2=3d+7y for y.
Answer:
y = (2-3d)/(7+c)
Step-by-step explanation:
-cy + 2 = 3d + 7y
To solve this equation in terms of y, we must first move all of the terms containing a y to one side of the equation and move all of the other terms to the other side.
Our first step is going to be to add cy to both sides of the equation.
- cy + cy + 2 = 3d + 7y + cy
2 = 3d + 7y + cy
Next, we can subtract 3d from both sides of the equation.
2 - 3d = 7y + cy
Next, we can factor out a y from the right side of the equation.
2 - 3d = y (7 + c)
Finally, we can divide both sides by the quantity (7+c) to get the y alone on the right side of the equation.
(2-3d)/(7+c) = y
Therefore, your answer is y = (2-3d)/(7+c).

If LaTeX: m\angle ABF=8s-6m ∠ A B F = 8 s − 6 and LaTeX: m\angle ABE=2\left(s+11\right)m ∠ A B E = 2 ( s + 11 ), find LaTeX: m\angle EBFm ∠ E B F. LaTeX: m\angle EBF=m ∠ E B F = [measure]LaTeX: ^\circ
Answer:
2(3s-14)Step-by-step explanation:
Given the angles ∠ABF=8s-6, ∠ABE = 2(s + 11), we are to find the angle ∠EBF. The following expression is true for the three angles;
∠ABF = ∠ABE + ∠EBF
Substituting the given angles into the equation to get the unknown;
8s-6 = 2(s + 11)+ ∠EBF
open the parenthesis
8s-6 = 2s + 22+ ∠EBF
∠EBF = 8s-6-2s-22
collect the like terms
∠EBF = 8s-2s-22-6
∠EBF = 6s-28
factor out the common multiple
∠EBF = 2(3s-14)
Hence the measure of angle ∠EBF is 2(3s-14)
One root of f(x)=x^3-4x^2-20x+48 is x = 6. What are all the factors of the function? Use the Remainder Theorem.
A. (x + 6)(x + 8)
B. (x – 6)(x – 8)
C. (x – 2)(x + 4)(x – 6)
D. (x + 2)(x – 4)(x + 6)
Answer:
(x - 6)(x + 4)(x - 2)
Step-by-step explanation:
since x = 6 is a root then (x - 6) is a factor
x³ - 4x² - 20x + 48 ÷ (x - 6)
= (x - 6)(x² + 2x - 8)
= (x - 6)(x + 4)(x - 2) ← factors of f(x)
By using the Remainder Theorem, all the factors of the function are,
⇒ (x - 6) (x + 2) (x - 4)
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
One root of function f (x) = x³ -4x² -20x + 48 is, x = 6.
Hence, (x - 6) is divide the function f (x) = x³ -4x² -20x + 48 as;
(x - 6) ) x³ -4x² -20x + 48 ( x² + 2x - 8
x³ - 6x²
--------------
2x² - 20x
2x² - 12x
-----------------
- 8x + 48
- 8x + 48
----------------
0
Hence, We get;
f (x) = x³ -4x² -20x + 48
f (x) = (x - 6) (x² + 2x - 8)
⇒ f (x) = (x - 6) (x² - 4x + 2x - 8)
⇒ f (x) = (x - 6) (x(x - 4) + 2(x - 4))
⇒ f (x) = (x - 6) (x + 2) (x - 4)
Thus., By using the Remainder Theorem, all the factors of the function are,
⇒ (x - 6) (x + 2) (x - 4)
