Answer:
x=23.5
Step-by-step explanation:
90=25-x/2+18
combine like terms
90=43-x/2
subtract 43 from both sides
47= -×/2
47/2= 23.5
x=23.5
or
90-25= 65
65-18=47
47/2=23.5
Suzie needs enough trim to cover the perimeter of the triangle. So she need enough to cover each side of 18. Thus 18 x 3 = 54 and 54 is your answer.
