Answer:
37.7
Step-by-step explanation:
Large circle =
r² =
5² = 78.54
Medium circle =
3²= 28.27
Small circle =
2²= 12.57
78.54-28.27-12.57 = 37.7

- The answer is <u>0</u><u>.</u>
- LHS = RHS, hence verified.
<u>Value of x (substitute 0 in the place of x).</u>

- So, value of x is <u>0</u><u>.</u>
15% off means 85% on so I would use .85x · 6 = total monthly cost to represent this problem. The dot represents times (I did not want to confuse things by using x)
Other ways to express this:
6 x .85x
6(.85x)
.85x (6)
