8 0

Answer:

See below ~

Step-by-step explanation:

Part A :

⇒ Total Length = Side 1 + Side 2

⇒ Total Length = (8x² - 5x - 2) + (7x - x² + 3)

⇒ Total Length = 7x² + 2x + 1

=============================================================

Part B :

⇒ Length of 3rd side = Perimeter - Part A solution

⇒ Length of 3rd side = 4x³ - 3x² + 2x - 6 - (7x² + 2x + 1)

⇒ Length of 3rd side = 4x³ - 10x² - 7

===========================================================

Part C :

⇒ Yes

⇒ It shows they are closed under addition and subtraction because no new values come into the equations

Answer:

20 inches

Step-by-step explanation:

Since the cape is trapezoid shaped and has an area of 600 in², the area of a trapezoid is given by

A =1/2(a + b)h where a = length along the top of the cape = 24 in, b =  length along the bottom of the cape = 36 in and h = height of the cape

So, h = 2A/(a + b)

= 2 × 600 in²/(24 in + 36 in)

= 1200 in²/60 in

= 20 in

So, the height of the cape is 20 inches
