Answer:
-296=2×2+20×-15that is the answer
Step-by-step explanation:
you need to calculate the equation step by step to get to the answer
You would use order or operations to solve this problem
4 to the second power is 16 -------> 12+16= 28
Your answer would be 28
Octagons have 8 sides. If each side is 5 feet then the perimeter is 40 feet. You add up the sides.
Answer:
vertex = (- 2, - 36)
Step-by-step explanation:
Given a parabola in standard form : y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= - 
f(x) = 5x² + 20x - 16 is in standard form
with a = 5, b = 20 and c = - 16
= - 
= - 2
Substitute x = - 2 into f(x) for corresponding y- coordinate
f(- 2) = 5(- 2)² +20(- 2) - 16 = 20 - 40 - 16 = - 36
vertex = (- 2, - 36)
