Answer:
triangle ABC is "not" a right-angled triangle
Step-by-step explanation:
AB=8cm
BC=5cm
perimeter = 22cm
CA = 22 - 8 - 5 = 9
8² + 5² = 89
9² = 81
AB² + BC² ≠ CA²
Y= -2x^3 is the answer

Answer:
(x+4)(x+4)
Step-by-step explanation:
The middle number is 8 and the last number is 16. Factoring means we want something like (x+_)(x+_). We need two numbers that add together to get 8 and multiply together to get 16. The number 4 works perfectly in this equation. That's why (x+4)(x+4) is the factor of the equation x^2 + 8x + 16.
