Answer:

Step-by-step explanation:
The zeros of the polynomial function are given us as -5,-1,2
If the zeros of a polynomial function are α,β,ω, the polynomial function can be obtained using the expression below:
f(x) = (x - α)(x - β)(x - ω)
where α = -5, β = -1, and ω = 2

<em>NB: To arrive at the answer, expand the brackets and after expansion, collect like terms to obtain the final answer</em>
The perimeter of a triangle is the sum of its side lengths.
Answer:
23
Step-by-step explanation:
Since 2/10 = 4/20, we know that a-3 = 20, so a = 20 + 3 = 23.
