What is the sum of 2m^2+3m-4 and m^2-3m-2
1) m^2-6
2)3m^2-6
3)3m^2+6m-6
4)m^2+6m-2
explain how you got your answer

3m² - 6

Step-by-step explanation:

Summing the 2 expressions

2m² + 3m - 4 + m² - 3m - 2 ← collect like terms

= (2m² + m²) + (3m - 3m) + (- 4 - 2)

= 3m² + 0 + (- 6) = 3m² - 6

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

part a

x     y

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

x       y

0       8

1       7.6

2       7.2
