A rectangle has a height of b3 + b2 and a width of b2 + 76 + 4.

zaharov [31]

Answer:

The area is:

${b}^{5} + 8 {b}^{4} + 11 {b}^{3} + 4 {b}^{2}$

Step-by-step explanation:

To find the area of a rectangle, multiply the width by the height (I'll be using x for b, as it is easier when writing the equations):

$a = ({x}^{ 3} + {x}^{2} )( {x}^{2} + 7x + 4) \\ a = {x}^{5} + 7{x}^{4} + 4 {x}^{3} \\ + {x}^{4} + 7 {x}^{3} + 4 {x}^{2} \\ a = {x}^{5} + 8 {x}^{4} + 11 {x}^{3} + 4 {x}^{2}$

Hey there! :D

So, those both will be equal to 180 degrees. Consecutive angles are supplementary.

2x-20+3x= 180

5x-20=180

Add 20 to both sides.

5x=200

x= 40

I hope this helps!
