Bella measured these outside temperatures for each of four days. day one: −14°f day two: −7°f day three: +3°f day four: −5°f which temperature was the coldest? a. −7°f b. −14°f c. −5°f d. +3°f

the most negative number is the lowest (or coldest)

-14< -7<-5<+3

Choice B

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
