Answer:
32
Step-by-step explanation:
You need to work backwards to solve this equation!
9 - 17 = -8
w / -4 = -8
32 / -4 = -8
Which means that w = 32
Answer:
74
Step-by-step explanation:
Answer:
13.73 sq mm
Step-by-step explanation:
Area of Square - Area of Circle = Area of Shaded Region
if radius of circle is 4 then diameter is 8
the diameter is the same as the length of each side of the square
so area of square = 8² or 64
Area of Circle = 16π
64 - 16π ≈ 13.73
Answer:
x+7y
Step-by-step explanation:
First off, lets split the question into both x and y.
3x - 2x for the x
11y - 4y for the y
You can solve both of them to get x + 7y
3x - 2x = x
11y - 4y = 7y
Then, add them back up and get x + 7y
