Hi there!

You can use distributive property to solve this equation.

These are the list of terms you have to multiply :
a × a² = a³
a × -ab = -a²b
a × b² = ab²
b × a² = a²b
b × -ab = -ab²
b × b² = b³

add all of those terms...
a³ - a²b + ab² +a²b -ab² + b³
simplify by adding like terms... (- a²b + a²b , ab² - ab²)

a³ + b³

Hope this helped!! :)

How many times longer is the length of the rectangle compared to the width? 14.4cm by 1.6cm
inna [77]
The answer is 8.

Explanation:

To find this out we would first subtract the width (1.6) from the length (14.4). 14.4 - 1.6 = 12.8. If we want to find out how many times which is how many time 1.6 to get 12.8, we would divide 12.8 by 1.6. The quotient is 8. Therefore, the length of the rectangle is 8 times that of the width.

I hope I helped and good luck!
