Answer:
x=2
Step-by-step explanation:
6x+7x−3x=13+7
10x=20
x=20/10
x=2
We need to multiply the factors (x - 2) and (x^2 + 9x + 10) to see if the product is the original expression given.
(x - 2)(x^2 + 9x + 10)
x^3 + 9x^2 + 10x - 2x^2 - 18x - 20
x^3 + 7x^2 - 8x - 20.
Since the product just found is not the original expression given, Jimmy is wrong.
I will complete the work on paper by synthetic division and post my answer.
After using synthetic division, the correct quotient is x^2 + 9x + 20.
The correct answer is D. Since the polygons are /similar/ and not /congruent/, C is not necessarily true.
Hope this helps.
