very morning, a bakery makes wheat bread. The staff bakes 20 loaves before the bakery opens at 7am and then bakes 10 more loaves every half-hour for the next three hours. If the number of loaves they have finished baking depends on the number of hours that have passed since the bakery opened, what is the range of this relation?

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

answer: i think you should do the math and pay attention in class : )

step-by-step explanation:

that is truly what   think but if i get the answer i will

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
