(x² + 4x - 45)/(x² + 10x + 9)
<span>
Numerator = N = x² + 4x - 45 </span>
= x² + 9x - 5x - 45
= (x² + 9x) - (5x + 45)
= x(x + 9) - 5(x + 9)
= (x + 9)(x - 5)
<span>
Denominator = D = x² + 10x + 9 </span>
= x² + x + 9x + 9
= (x² + x) + (9x + 9)
= x(x + 1) + 9(x + 1)
= (x + 1)(x + 9)
<span>
Hence, the given expr. = N/D </span>
= {(x + 9)(x - 5)}/{(x + 1)(x + 9)
= (x - 5)/(x + 1)
<span>
Restrictions : x ≠ - 1, x = 5 </span>
I hope my answer has come to your help. Thank you for posting your question here in Brainly.
Answer:

Step-by-step explanation:
A = LW for W
A/L = LW/L = A/L=W
/ = fraction bars but i couldn't use fraction bars
hopefully this helped ! :)
Answer:
Step-by-step explanation:
so let's start with what we know:
now to get it into non mixxed numbers:
2*3 = 6
6+1
_____
2*3=6
6+2=8
______
now to cross mutiply them:
7*3
