Answer:
7(7x + 2)
Step-by-step explanation:
when distributed it will be 49x + 14
Answer:
B: 210
C: 450
Step-by-step explanation:
You just need to multiply the two numbers overlapping in the box. For B, the two numbers for that box are 30 and 7, therefore you must multiply them together to get 210. For C, the numbers are 90 and 5, when multiplied equals 450. Hope that helps!
Answer:
The correct option is A.
Step-by-step explanation:
Domain:
The expression in the denominator is x^2-2x-3
x² - 2x-3 ≠0
-3 = +1 -4
(x²-2x+1)-4 ≠0
(x²-2x+1)=(x-1)²
(x-1)² - (2)² ≠0
∴a²-b² =(a-b)(a+b)
(x-1-2)(x-1+2) ≠0
(x-3)(x+1) ≠0
x≠3 for all x≠ -1
So there is a hole at x=3 and an asymptote at x= -1, so Option B is wrong
Asymptote:
x-3/x^2-2x-3
We know that denominator is equal to (x-3)(x+1)
x-3/(x-3)(x+1)
x-3 will be cancelled out by x-3
1/x+1
We have asymptote at x=-1 and hole at x=3, therefore the correct option is A....
Answer: The first option, the one in orange.
