Add: ( 2x^2 + 6x + 4) and ( 5x^2 - 5x + 10)

7x² + x + 14

Step-by-step explanation:

(2x² + 6x + 4) + (5x² - 5x + 10)

Remove parentheses

2x² + 6x + 4 + 5x² - 5x + 10

Put like terms together.

2x² + 5x² + 6x - 5x + 4 + 10

Simplify.

7x² + x + 14

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

step-by-step explanation:

if x = 2 you have to find x to finish the problem
