Answer: a = 23, b = 21, c = 136
Step-by-step explanation:
The diagram shows that all the sides of the rectangle are congruent. Since the perimeter all of the sides added up, all you have to do is divide the perimeter by 4.
Therefore, the perimeter, which is 16x + 24, can be divided by 4 to find the length of one side.
16x + 24/4 = length of one side. So, the length of one side is 4x + 6.
Hope this helped!
Start by getting all terms with x on one side and all terms without on the other.
6x+7=8x-15
subtract 6x from both sides
7=2x-15
add 15 to both sides
22=2x
divide both sides by 2
11=x
Answer:
14
Step-by-step explanation:
3 times 14 equals 42, and 42 divided by 2 is 21. 21 divided by 3 is 7. :)
