Not sure about the last question
Answer:
I believe that the answer would be 1/5.
Step-by-step explanation:
The perimeter of a triangle is:
P = a + b + c
We are given that:
b = a + 3
c = 2 a – 3
Therefore:
68 = a + a + 3 + 2 a – 3
68 = 4 a
a = 17
and,
b = a + 3 = 20
<span>c = 2a – 3 = 31</span>
" the quotient " means divide
(x/3) - 4 <== ur expression
