0.009 i think this is the answer
(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:
The value of the digit 7 in 0.7 is tenths.
Answer:
x=38
Step-by-step explanation:
Vertically opposite angles are equal, therefore equate the 2 angles opposite each other.
2x+5=3x-33
2x-3x= -33-5
-x= -38
x=38
Answer:
x = -4
Step-by-step explanation:
y = 3x - 1
Replace all instances of Y into the second quation.
2x - (3x-1) = 5
2x -3x +1 = 5
-x = 4
x= -4
