X^2 + 11x + 30

Step-by-step explanation:

x*x= x^2

x*6= 6x

x*5= 5x

6*5= 30

x^2 +6x+5x+30

Combine like terms

x^2 + 11x + 30

These are rectangles, so the area of this shape is a sum of areas:

- blue: a = x, b = x, so area: x · x = x²

- pink: a = 6, b = x, so area: 6 · x = 6x

- green: a = 5, b = x, so 5 · x = 5x

- orange: a = 6, b = 5, so 6 · 5 = 30

The area of the entire rectangle is: x² + 6x + 5x + 30 = x² + 11x + 30

We can also count this area by multiplication of side lengths of big rectangle:

a = x + 6, b = x + 5

then the area is:

(x + 6)(x + 5) = x · x + x · 5 + 6 · x + 6 · 5 = x² + 5x + 6x + 30 =

= x² + 11x + 30

no not all of them.

step-by-step explanation:

some of them have a square base.

what i would say the best answer is a. 40.5
