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 )
Answer:
violates the rules or bedmas
Step-by-step explanation:
When doing questions like these, bedmas comes into play. althought multiplication and division are the same in terms of priority, you should do the one that comes first when reading the equation/formula left to right.
this would mean you would do 2 ÷ 3 and the answer would be multiplied by 12.

Answer:
66
Step-by-step explanation:
Is is wanting you to find the missing number, which is "x".
An equation for this is x-6=60
The is only one number that can be x.
So, I added 6 and 60, I got 66.
Than I subtracted 66 and 6, and got 60.
I know that 66 is the correct answer.
