Answer:

(x - 2)(x - 11)

Step-by-step explanation:

We have a polynomial and are asked to factor it.

Polynomial : x^2 - 13x + 22

Usually a trick I follow when factoring is that for c (in this case 22). You need to find two numbers that will multiply to it. And for b (in this case -13) you will need to find two numbers that will add to it, the same numbers you multipled for c.

So

x * y = 22

x + y = -13

These two numbers are -11 and -2.

valina [46]
The perimeter of an equilateral triangle is just 3s as all the sides are, well, equal :) so

P=3s and we are told that P=24.6 so

3s=24.6
