Answer: 100 - 24x
Step-by-step explanation:
The formula for calculating the perimeter of a square is given by :
P = 4l , where l is the length of the side.
Perimeter of square A will be
P = 4 ( 2x - 7 )
P = 8x - 28
Perimeter of square B will be ;
P = 4 ( -4x + 18 )
P = - 16x + 72
Perimeter of square B - Perimeter of square A implies
-16x + 72 - ( 8x - 28 )
-16x + 72 - 8x + 28
collecting the like terms
-16x - 8x + 72 + 28
-24x + 100
⇒ 100 - 24x
I believe that answer is B. (The second one)
Hope this helped !!
To divide fractions be multiply by the resiprical
4 6 24
--- x ---- = ------
1 7 7
then simplify into a mixed number
3 3/7
If you divide 67 by 50 you are left with 1.34 if you turn that decimal into a percent it turns into 134%
Red I know because the smaller the number the bigger the fraction
