Review: to simplify an expression, combine like terms by adding orsubtracting coefficients only. like terms have the same variable (letter orsymbol that represents a quantity).example: 17a + 4 - 5a - 3 = (17a - 5a) + (4-3) = 12a + 1simplify this expression. 10b + 7 - 3 - 2

10b + 2

Step-by-step explanation:

To simplify this expression. 10b + 7 - 3 - 2​ use the sample you demonstrated above to simplify it

10b + 7 -3 -2

combine the like terms

10b + 7 - 5

10b + 2

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.

the answer is 844

step-by-step explanation:
