Answer:
x^2 -x -2 = (x -2)(x +1)
Step-by-step explanation:
To factor x^2 -x -2, you look for factors of -2 that have a sum of -1:
-2 = (-1)(2) = (1)(-2) . . . . . the latter pair has a sum of -1
Then these are the constants in the binomial factors:
x^2 -x -2 = (x +1)(x -2)

<em>Comment on the question</em>
The fact that x^2 +3x -4 is modeled with algebra tiles seems to be irrelevant to the question that is actually asked.
Answer:
14.45
Step-by-step explanation:
x^2+(7.1)^2=(16.1)^2
×^2+50.41=259.21
x^2=208.8
sqrt(x^2)=sqrt(208.8)
x=14.45
check.
14.45^2 + 7.1^2 = 16.1^2

Based on the information about the percentage, the commission that will be paid will be $3050.
<h3>How to solve percentage</h3>
From the information given, it was stated that there's a 10 percent on first $5,000 and 15% over $5,000.
The total graduate commission on $22,000 will be:
= (10% × $5000) + (15% × $17000)
= (0.1 × $5000) + (0.15 × $17000)
= $500 + $2550
= $3050
