Answer:
A Variable
Step-by-step explanation:
Variables are used to mark an unknown value. Common math problems ask you to solve for it.
For example in 5x+23=45, 'x' is the variable.
A constant is a number without a variable.

Answer:
The distributive property of multiplication
Step-by-step explanation:
<u>explanation</u>:-
The distributive property of multiplication states that when a number is multiplied by the sum of two numbers, the first can be distributed to both of those numbers and multiplied by each of them separately,then adding the two products together for the same result as multiplying the first number by sum.
a(b+c) = a.b + a.c
so -2 ( -3+7) = -2(-3) + (-2)(7)
-8 = 6 -14
-8 = - 8
give data we will use distributive property of multiplication
