Answer:
8 years old and Laura is 32
Step-by-step explanation:t
Let the daughter be equal to "x".
Laura would be "4x".
In 16 years Laura will be twice as old can be expressed as this:
4x+16=2(x+16)
Solve:
4x+16=2x+32
2x=16
x=8
Therefore at present time, the daughter is 8 years old and Laura is 32.
solve for x
5 - 2x^2 = -15

The volume of a rectangular prism, in cubic inches, is given by the expression
x^3+3x^2-4x+7. The volume of the smaller prism is given by the expression
5x^3-6x^2-6x-17. How much great is the volume of the larger rectangular prism is than the smaller prism?
Answer:
-4x³ + 9x² + 2x + 24
Step-by-step explanation:
To find how much great is the volume of the larger rectangular prism than the smaller prism, we need to subtract
Volume of larger rectangular prism - Volume of smaller prism =
= x³ + 3x² - 4x + 7 - (5x³ - 6x² - 6x - 17)
To remove the parenthesis,multiply each term of the smaller prism by (-1)
= x³ + 3x²- 4x + 7 - 5x³ + 6x² + 6x + 17
= x³ -5x³ + 3x² + 6x² - 4x + 6x +7 + 17 {Combine like terms}
= -4x³ + 9x² + 2x + 24

Luke has a cylinder with a radius of 5 inches and a height of 6 inches. What is the volume of his cylinder in cubic inches?
Answer:
471.24 cubic inches
Step-by-step explanation:
The formula for the volume of a cylinder =
πr²h
r = Radius = 5 in
h = Height = 6 in
Hence,
Volume = π × (5 in)² × 6 in
= 471.24 cubic inches
Therefore, the volume of his cylinder in cubic inches = 471.24 cubic inches
A tree that is 8 feet tall is growing at a rate of 2 feet each year. A tree that is 16 feet tall is growing at a rate of 1 1/2 feet each year. Enter the number of years it will take the two trees to reach the same height
Answer: 8.
This is because for every 2 years the 10 foot tree will grow one foot and for every year the 8 foot tree will grow one foot.
It takes 8 years fort the 10 ft tree to be:16
This is because you do:
2+2+2+2+2+2+2+2=16
It takes 8 years for the 8 food tree to be: 16
You do:
2+2+2+2+2+2+2+2=16 and we added it 8 times and in 8 years it will be 16

There were f frogs in a pond. 36 of the frogs hopped away. Write the expression that shows how many frogs are in the pond now.
Answer: f - 36
Step-by-step explanation:
Number of frogs in the pond originally was f.
Then 36 of them hopped away which means that these 36 have to be subtracted from the original f to find out the number of frogs still in the bond.
Expression is therefore:
= Number of frogs originally in the pond - Number of frogs that left
= f - 36
