A number plus -3 is 8

a number (x) plus (+) -3 (-3) is (=) 8 (8).

Step-by-step explanation:

x+(-3)=8

x=11

A number: since we don't know what the exact number is we can represent that number with a variable. Let's use x...

x + (-3) = 8

You can also write this as...

x - 3 = 8

They both mean the same thing :)

When you solve...

x - 3 = 8

add 3 on both sides...

x = 11

Your answers are...

x + (-3) = 8

x = 11

Hope this helps :)

step-by-step explanation:

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
