Answer:
x= 16.6
Step-by-step explanation:
The circle is unnecessary. You can just use Pythag Theorem
so
9^2+14^2= c^2
81 + 196 = 277
square root 277
16.64
round to the nearest tenth...
16.6
Answer:

Step-by-step explanation:
We are required to solve for c in the equation: 
Step 1: Collect like terms

Step 2: Find the Lowest Common Multiple of the denominators
LCM of 8 and 5 is 40
Step 3: Multiply all through by 40

Step 4: Simplify
40c=32-5
40c=27
Step 5: Divide both sides by 40 and simplify if possible.

Answer: E. None of the above
Step-by-step explanation:
The equation to solve the problem should look like...2x = $2.91 / 3
You will find the side by 28 ÷ 4 = 7 ft because a square has 4 equal sides.
Then we will do side × side to find the area of a square, so 7 × 7 = 49 ft²
So the answer is 49ft²
9 mph because if it was 4/5 miles in 1/10 of an hour you just multiply it by 10 to get an hour and if you multiply 4/5 x 10 equals 40/5. simplified it is 9
