Answer:
(d) (-2, 6)
Step-by-step explanation:
We can rewrite the function using vertex form.
f(x) = (x^2 +4x) +10
f(x) = (x^2 +4x +4) +10 -4 . . . . . . . add and subtract (4/2)^2
f(x) = (x +2)^2 +6
Compare to vertex form:
f(x) = (x -h)^2 +k
we see that (h, k) = (-2, 6) . . . . the vertex

<em>Additional comment</em>
The value added and subtracted is the square of half the x-coefficient. Inside parentheses, that value "completes the square". Outside parentheses, that value ensures the overall function remains unchanged.
For part A :draw 5 separate rectangles, then draw 4 sections in each separate rectangle. Finally, shade in one of the the four pieces in each of the 5 rectangles.
For part B : Jareld wants to give his 5 candy bars with his friends. Each friend wants to get 1/4 of a candy bar. How many people will share the 5 candy bars using the facts provided?
For part C : (So whenever you do division between any type of fraction,whole number or mixed number) you do the strategy keep change flip where first you keep the fraction 5/1 which equals 5 as a whole number. Then you change the division symbol in the provided equation to a multiplication symbol (x). Then you flip the fraction 1/4 to 4/1. Then you plug in all of the numbers into your new and improved statement. 5/1 * 4/1=y. Y=20

Answer:
20 degrees
Step-by-step explanation:
The sum of these two angles is 180 degrees. Therefore, the equation to solve this problem would be 2x + 6x + 20 = 180. The answer is 20 degrees.
A^2 - 4a + 4
