Answer:
The first expression can be rewritten as
35 {b}^{2} = 5 \times 7 \times {b}^{2}35b
2
=5×7×b
2
The second expression is rewritten as
15 {b}^{3} = 3 \times 5 {b}^{3}15b
3
=3×5b
3
The third expression is
5b = 5 \times b5b=5×b
The greatest common factor is the product of the least powers of the common factors.
To find the perimeter of the triangle you need to add up all the side lengths

Now move like terms, the ones with x and ones without, next to each other.
(You can skip this step, but I think it makes it easier to understand.)

Now just add like terms to get your answer.
30 3/4 + 12 1/4 + 16 1/4 = 59 1/4
72 - 59 1/4 = 12 3/4
Buenos tardes!
