Answer:
A
Step-by-step explanation:
When multiplying numbers with exponents, the exponents add together. This means that the correct answer is letter A.
Answer:
Width = 2x²
Length = 10
Step-by-step explanation:
The greatest common monomial factor of 14x² and 6x² is 2x² so the width is 2x².
Width = 2x²
Length = (14x² ÷ 2x²) + (6x² ÷ 2x²)
= 7 + 3
= 10
Answer:
vertex = (- 10, - 10 )
Step-by-step explanation:
The equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square.
Given
h(x) = x² + 20x + 90
add/subtract ( half the coefficient of the x- term )²
h(x) = x² + 2(10)x + 100 - 100 + 90
= (x + 10)² - 10 ← in vertex form
with (h, k ) = (- 10, - 10 )
