Answer:
We need to factor this trinomial by grouping.
The first step in this process consists of splitting the middle term into two terms.
In our example, has been split into and .
Notice that one common factor can be factored from the first 2 terms, and another from the second 2 terms

Answer:
4 3/20 cm
Step-by-step explanation:
Perimeter of a triangle = 16 3/5 cm
Side A = 5 7/10 cm
Side B = 6 3/4 cm
Side C = x cm
Perimeter of a triangle = side A + side B + side C
16 3/5 = 5 7/10 + 6 3/4 + x
83/5 = 57/10 + 27/4 + x
83/5 = (114+135) / 20 + x
83/5 = 249/20 + x
x = 83/5 - 249/20
= (332-249) / 20
= 83/20
= 4 3/20
x = 4 3/20 cm
Side C = x cm = 4 3/20 cm
I think it represents where something is starting from, like something growing up (a chart with rising numbers)
