Whats the answer? I will mark brainliest! please help!

D) 12

Step-by-step explanation:

Since PR is a midsegment of ABC, you need 2 of them.

(x + 3)2 = x + 9                   Distribute 2 to (x + 3)

2x + 6 = x + 9

- x          - x                         Subtract x from both sides

x + 6 = 9

  - 6   - 6                            Subtract 6 from both sides

x = 3

Plug this into the equation of segment AC

3 + 9

12 is the length of segment AC

D) 12

Step-by-step explanation:

Given: Segment PR is a midsegment of triangle ABC.

So if PR is a midsegment the triangle, then we expect the base segment, AC, to be double the length of segment PR;

I.e 2(x + 3) = x + 9

2x + 6 = x + 9

2x - x = 9 - 6

x = 3

So the length of segment AC is 3 + 9 = 12

$18 was the price of the t-shirt

step-by-step explanation:

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
