Answer:
1.) 9
2.) 20
Step-by-step explanation:
1.) 39 is incorrect because they didn't follow the PEMDAS rule.
They subtracted 2 from 15 which is 13, and then they multiplied 13 by 3.
<u>The correct way is to multiply 2 times 3 which is 6, and then subtract 6 from 15 which is 9.</u>

2.) 12 is incorrect because they didn't use PEMDAS.
They added 8 to 16 which is 24, and then divided 24 by 2.
<u>The correct way is to divide 8 by 2 which is 4, and then add for to 16 which 20.</u>
Answer:
The value of x is -31.
Step-by-step explanation:
To solve this, follow the order of operations for solving equations. The step-by-step is listed below.
5(x - 4) + 2 = -173 ----> Subtract 2 from both sides
5(x - 4) = -175 ----> Divide both sides by 5
x - 4 = -35 ----> Add 4 to both sides
x = -31
C' ( 0, 3)
A' ( 2 , 1)
C'A' = CA
C'A' = √(2^2 + 2^2) = √8 = 2√2
C'A' = CA = 2√2
Answer:
A=5
B=4
Step-by-step explanatation
so the 3ft at the front and the 8ft at the back, you do 8-3 which is 5 which will be A and on the side, it is 8ft and since the corner angle is 4ft then B will be 8-4 which is 4
