Answer:

So x = 20

Step-by-step explanation:

AB + BC = AC sum of a segment is sum of its pieces

AB + AB = AC B is the midpoint, so AB = BC

2x + 2x = 3x + 20 putting in for AB (twice!) and AC

4x = 3x + 20 collect like terms

x = 20 subtract 3x on both sides.

Please help me thanks please Will give you brainlest

Answer:

224

Step-by-step explanation:

Base:

A = Bh

A = 8(8) = 64

Sides:

A = 1/2 Bh

A = 1/2 8(10)

A = 40

Then you do 40(4) because there are 4 sides:

40 (4) = 160

Then you add up the base and the sides:

160 + 64 = 224

(I think this is the right answer)
