A rectangle has a perimeter of 104cm find the width on the left is side a and side b is the length the first part of the equation is 2(3x)+2(2x+7)=104cm then find the width using 2x+7=____ I know that I keep putting this up but for some reason some of the answers are not coming to my email know that one of you sent the answer by sending a thank you but I did not receive them I thank for your patients
Since the given equation for the perimeter is: 2(3x) + 2(2x + 7) = 104, we get:
6x + 4x + 14 =104
10x = 104 - 14
10x = 90
x =
, or 9 cm
With 2x + 7 given as the width, width = 2(9) + 7, or 18 + 7, or
cm
