Expression 1: 3(x+5)

Expression 2: 3x+{?}

Answer 1

The number that makes the algebraic expressions equivalent is 15.

Answer 2

Enter the numbers that make the algebraic expressions equivalent.(1 point)

Expression 1: −6m+13+10m−8

Expression 2: [?]m+[?]

Answer 3

To make the algebraic expressions equivalent, we need to combine like terms.

Expression 1 can be simplified as follows:
-6m + 13 + 10m - 8 = 4m + 5

Therefore, expression 2 should be equivalent to 4m + 5. The numbers that should replace the question marks are 4 and 5, respectively.
