Can someone just answer this asap for ! the quadratic expression x^2 + mx + 18 can be factored as (x + g)(x + h), where m, g, and h are are integers. pat wrote that m could be equal to -11. grace wrote that m could be equal to 7. which student is correct? a. only pat b. only grace c. both pat and grace d. neither pat nor grace

A

Step-by-step explanation:

x² + Mx + 18

                ∧

             1 +  18 = 19  or   -1 +  -18 = -19

             2 +  9 = 11   or   -2 +  -9 = -11

             3  + 6 = 9    or   -3  + -6 = -9

M can be +/- {19, 11, or 9}.  

it would be 6xy and -16xy.

part a

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
