Convert from standard form to vertex form and pls show work :) 1. f(x) = 4x²+ 8x -3
2. f(x) = -x -4 + 1

1/4 because there is 4 grades.

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

i think the length is 12 and the width is 17
