Answer:

15 $x^{2}$ + 7x + 12

Step-by-step explanation:

(6x^2 + 7x + 2) - (-9x^2 - 10)

Flip the sign:

- (-9x^2 - 10) becomes + 9x^2 + 10

Combine like terms:

6x^2 + 7x + 2 + 9x^2 + 10

6x^2 + 9x^2 = 15x^2

2 + 10 = 12

Put it all together:

15x^2 + 7x + 12

Solvefor x. x+3/5 =2

oee [108]

Answer: x=7/5 or 1 2/5

Step-by-step explanation:

Given

x+3/5=2

Subtract 3/5 on both sides

x+3/5-3/5=2-3/5

x=10/5-3/5 (This is to convert 2, as a integer, to a fraction in order to ease the

x=7/5 operation)
