Answer:
86
Step-by-step explanation:
Given, x = 5
length of a rectangle = 6x-4 = 6 * 5 - 4 = 30-4 = 26
width of a rectangle = 3x + 2 = 3 * 5 + 2 = 15 + 2 = 17
Now , finding the perimeter of the rectangle :
Perimeter of a rectangle = 2 ( length + width )
= 2 ( 26 + 17 )
= 2 * 43
= 86
Hope I helped!

Answer:
b
Step-by-step explanation:
We can write out a formula in order to solve this. Since sum represents addition, if x represents the unknown number, we can write the formula: x+51=-21. Then, to solve for x, you would subtract 51 from both sides to get x=-72 which is the final answer.
