Question

Combine like terms to solve for the variable. check your answer
9h+3-5h-8+3h-5=3h+2-6h+8-5h-5

If the perimeter of a triangle is 94 and the sides are (3d+2) in., (2d+1) in. and (5d-9) in., find the following
a. what is the value of d?
b.what is the length of each side?
Please help i got stuck on this two last question please

Answer 1

9h+3-5h-8+3h-5=3h+2-6h+8-5h-5
9h-5h+3h-3h+6h+ 5h = -3+8+5+2+ 8-5
15h = 15
h = 1
checking
LHs = 9+3-5-8+3-5 = -3
RHS = 3+2-6+8-5-5 = -3
OK

Answer 2

first add um the "H" numbers
and add up the normal numbers(no H)

Answer 3

3d+2+2d+1+5d-9 = 94
10d = 94 - 2 -1 + 9 = 100
d = 10

length of sides = 32, 21 and 41
