To find the perimeter, you must add all sides of the shape. Hope this Helps!
X^2 + 4x - 12
u see that last sign in ur problem....the negative....thats tells us that ur 2 factors will each have different signs. And u see ur first sign...the positive..that tells us that ur larger number will be positive. Now we have to find 2 numbers, then when added = 4 and when multiplied = -12.
6 and -2 are ur numbers...
so when factored, it is : (x + 6)(x - 2) <==
B) 50 - c = 16; $34 spent on clothes
50 - c = 16
Subtract 16 from both sides.
34 - c = 0
Add c on both sides.
34 = c
So, they spent $34 on clothes.

Mean:
Add all the numbers:
13 + 17 + 15 + 18 + 21 + 13 + 20 + = 16.7
16.7 + 3.7 = 20.4
Mean = 20.4
Median:
Order the numbers:
13, 13, 15, 17, 18, 20, 21
The median, or middle number is 17.
17 + 3.7 = 20.7
Median = 20.7
Mode:
The number that repeats the most is 13.
13 + 3.7 = 16.7
Mode = 16.7
Range:
Highest Number = 21
Lowest Number = 13
21 - 13 = 8
Range = 8
The answer choice that matches is choice A.
Hope this helped☺☺
