Answer:
Answer choice C
Step-by-step explanation:
Answer:
(a) (x+9) (x+2)
(b)(x-2) (x-3)
(c) (x+2) (x+3)
(f) (x-9) (x-2)
(2) x2+11x+18
(3) x2-7x - 18
(6) x2+5x+6
Step-by-step explanation:
The value of x is equal to 14.
Since the bottom side is equal to 3 of the small triangle and the side of the larger triangle is equal to 9, that means that it was dilated by a factor of 3, since 3 * 3 = 9
So, the other side of 5, of the smaller triangle needs to be also be dilated by a factor of 3, so the new side is 15.
The larger triangle tells us that the side is x + 1, but we know that it is equal to 15. Since they are the same, we make them equal and solve for x
So, 15 = x + 1
We subtract 1 to isolate x and we get
14 = x
So, x is equals to 14.
I hope this helps.
