I got it as 4 when calculating all have the same number which is 133
Answer:
7.14 in. sq
Step-by-step explanation:
First find the area of the square; 2x2=4
Now find the area of the semi-circle; radius = 1.
1 squared= 1 Now multiply by 3.14 which equals 3.14
Now divide by 2 because it's a semi-circle, you get 1.57.
Multiply 1.57 by 2 because you have 2 semi-circles, the would equal 3.14
Add 4+3.14 and you get 7.14
The area of the composite figure is 7.14 in. sq
We have the triangle 30° - 60° - 90°.
The lenght of the sides are in proportion: 
Y = -7x + 2
y = 9x - 14
-7x + 2 = 9x - 14
14 + 2 = 9x + 7x
16 = 16x
1 = x
y = -7x + 2
y = -7(1) + 2
y = -7 + 2
y = -5
solution is : (1,-5) <==
2.5(10x - 16) = 5
2.5 is multiplying on the left, then it will divide on the right
10x - 16 = 5/2.5
10x - 16 = 2
16 is subtracting on the left, then it will add on the right
10x = 2 + 16
10x = 18
10 is multiplying on the left, then it will divide on the right
x = 18/10
x = 1.8
