Simplify the expression.

Anna71 [15]

Since we have a cubic root, we're interested in factoring cubes inside the root, so that we can take them out. If we factor 648, we have

$648=2^3\times 3^4=2^3\times 3^3\times 3 = (2\times 3)^3\times 3 = 3\times 6^3$

So, we have

$3x\sqrt[3]{648 x^4 y^8} = \sqrt[3]{3\times 6^3\cdot x^3\cdot x \cdot y^6\cdot y^2}=3x\cdot 6\cdot x\cdot y^2\sqrt[3]{3\cdot x\cdot y^2}$

And the result simplifies to

$18x^2y^2\sqrt[3]{3xy^2}$

April and Amy have a combination age oh 53.Amy is 9 years younger than April.what are April and Amy ages.

Lostsunrise [7]

If the total age of both April and Amy are 53

And Amy is 9 years younger than april.

Then to solve for Amy's age you would subtract 9 from 53 and divide by 2

which equals 22

Since amy is 9 years younger than April, then April's age is Amy's age 22 + 9 which gives you 31

April's age is 31 and Amy's age is 22

Soham's video game system measures 8 inches long, 6 inches wide, and 2 inches tall. Sean's video game system measures 1 inch lon

Lady_Fox [76]

Answer:

Combined volume of the two game systems $=416$ cubic inches

Step-by-step explanation:

Volume of a cuboid = length × breadth × height

Soham's video game system measures 8 inches long, 6 inches wide, and 2 inches tall.

So,

Volume of Soham's video game system = 8 × 6 × 2 = $96$ cubic inches

As Sean's video game system measures 1 inch longer on all sides,

the video game system measures $8+2=10$ inches long, $6+2=8$ inches wide, and $2+2=4$ inches tall.

Volume of the video game system = 10 × 8 × 4 = $320$ cubic inches.

Therefore,

Combined volume of the two game systems = $96+320=416$ cubic inches
