Answer:
Jamie is correct
Step-by-step explanation:
Jamie is correct.
Example: isosceles triangle ABC AB=AC
∠B = ∠C ∠A + ∠B + ∠C = 180°
if ∠A = x ∠B = ∠C = 1/2 * ( 180° - x)
if ∠B or ∠C = x ∠A = 180° - 2x
Answer:

Step-by-step explanation:
Multiply the equations together
(5x+4)(5x^2-7x-2)
25x^3-35x^2-10x+20x^2-28x-8
Add like terms
25x^3-15x^2-38x-8
