In this equation, identify the following: -3x + 7

-3 = Constant, co-efficient, variable

x = Constant, co-efficient, variable

+ 7 = Constant, co-efficient, variable

Step-by-step explanation:

In this EXPRESSION , and not equation!!!

- 3 is a coefficient

x is a variable

7 is a constant

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
