Answer:
Step-by-step explanation:
√x - 7 = 3 {add 7 to bothe sides}
√x - 7 + 7 = 3 + 7
√x + 0 = 10
√x = 10
Square both sides,
(√x)² = 10²
x = 100

9-4=-5 would be the smallest answer
1.70 - 0.45 = 1.25
1500 ÷ 1.25 = 1200

Step-by-step explanation:
Let's define 3 areas:
- S = area of semicircle with radius 6 in (diameter AB)
- T = area of quarter circle with radius 6√2 in (radius AC)
- U = area of triangle ABC (side lengths 6√2)
The white space between the "moon" and the triangle has area ...
white = T - U
Then the area of the "moon" shape is ...
moon = S -white = S -(T -U) = S -T +U
The area we're asked to find is ...
moon - triangle = (S -T +U) -U = S -T
__
The formula for the area of a circle of radius r is ...
A = πr²
So, ...
S = (1/2)π(6 in)² = 18π in²
and
T = (1/4)π(6√2 in)² = 18π in²
The difference in areas is S -T = (18π in²) -(18π in²) = 0.
There is no difference between the areas of the "moon" and the triangle.
