9. A: 47
Step-by-step explanation:
Quesiton 7:
To find perimeter we add all the sides together.
x+2x+2x+5=145
Combine all the x's.
5x+5=145
To isolate the constants, subtract 5 from both sides.
5x=140
Now divide both sides by 5 to isolate the x.
x=28
The questions asks for the length of AC, so to find that we need to insert our new x.
AC= 2(28)+5
56+5=61
The Solution:
Given:
Each withdrawal by Brandon = $x
ATM charge per transaction = $2
Required:
To find an expression for Brandon's total withdrawal if he withdraws the same amount once a week for 7 weeks.
Step 1:
We shall find the total amount of each withdrawal, that is, the sum of the amount withdrawn and the ATM charge for the transaction.
Step 2:
Finding the required total amount, we have:

Hello!
A circle centered at the point (h,k) with a radius (r) has the following formula:
(x – h)² + (y – k)² = r²
Substitute any known values into the equation above:
(x – 4)² + (y – (-1))² = 3²
Simplify both sides:
(x – 4)² + (y + 1)² = 9
This is the equation of the given circle. The answer is B.
I hope this helps!
