Answer:
44.34
Step-by-step explanation:



Factorize the quadratic trinomial
by the rule:

1. Find the roots:

2. Factorize the polynomial:

3. Only factor x-2 is given in options, then the correct choice is B.
Answer:
A.
Step-by-step explanation:
The x-intercepts are the points where the x value is zero. In this case, to find the "zeros" of the function, set each factor to zero. x-5 -> x=5. x-6 -> x=6. x+4 -> x=-4.
91.5 is the perimeter. It's just 5a.
You would take 7.5 and divide it by 2 which will give you C. 3.75
