5x + 4x^2(2x+7) - 6x^2 - 9x + (x+3)(x-8)
5x + 8x^3 + 21x^2 - 6x^2 - 9x + x^2 - 5x - 24
8x^3 + 16x^2- 9x - 24
Answer:
∠B=∠D, ∠C=∠E, ∠A=F.
Step-by-step explanation
FE/AC=6/8=3/4, FD/AB=9/12=3/4,DE/BC=13.5/18=3/4. Since all proportions are equal to 3/4, the corresponding side lengths are proportional.
Answer:
1. Scalene 2.Acute 3.Obtuse 4.equilateral 5.right
Step-by-step explanation:
Have a good day!
Part A: Any thing to the 0 power is one so x = 0
Part B: 5^0 = 1 so it is 1^x = 1
1 to any power is 1 so x is all numbers.
