The shape is composed of three squares and two semicircles. Select all the expressions that correctly calculate the perimeter of the shape. #2 Group of answer choices 80+20π 40+20π 10+10+10π+10+10+10π 120+20π 300+100π

120 + 20π

Step-by-step explanation:

Find the image of the question attached.

For the square;

Perimeter of a square = 4L

L is the side length of the square

From the diagram, L = 10

Perimeter of a square = 4(10) = 40

Perimeter of 3 squares = 3(40) = 120

For the semicircles:

Perimeter of a semicircle = 2πr/2 = πr

From the diagram;

L = radius of the semicircle = 10

Perimeter of a semicircle = π(10)

Perimeter of a semicircle = 10π

Perimeter of the two semicircles = 2(10π) = 20π

perimeter of the shape = perimeter of 3squares + 2 semicircles

perimeter of the shape = 120 + 20π

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
