Answer:

216.5

Step-by-step explanation:

It helps to divide the shape into a rectangle and a triangle

A(rectangle)=bh

b=17

h=8.5

17 x 8.5 = 144.5

A(triangle)=1/2 bh

b=12

h=12

1/2 x 12 x 12 =72

72 + 144.5 = 216.5

GIVING THE BRAINLIEST ANSWER
Ahat [919]

Answer:

(6,3)

Step-by-step explanation:

y=2/3 x - 1

y=-1/2 x + 6

Since both equations are equal to y, we can set them equal

2/3 x - 1 =-1/2 x + 6

We have fractions, so I will multiply by 6 to clear the fractions

6(2/3 x - 1) =(-1/2 x + 6)6

Distribute

4x -6 = -3x +36

Add 3x to each side

4x+3x -6 = -3x+3x +36

7x -6 = 36

Add 6 to each side

7x-6+6 = 36+6

7x = 42

Divide each side by 7

7x/7 = 42/7

x =6

Now we need to find y

y =2/3x -1

y = 2/3(6) -1

y = 4-1

y=3
