write and simplify a polynomial expression for the surface area of each figure.

2(2x * 2x+1) + 2(2x * x+3) + 2(2x+1 * x+3)

Use distributive property on each set of terms:

2(4x^2+2x) + 2(2x^2+6x) + 2(2x^2 +7x+3)

Use the distributive property again:

8x^2 + 4x + 4x^2 +12x + 4x^2 +14x +6

Now simplify by combining like terms:

16x^2 + 30x +6

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
