The value of -2−(−10) in a addtition expression is 8.
<h3>What is an expression?</h3>
Expression simply refers to the mathematical statements which have at least two terms which are related by an operator and contain either numbers, variables, or both.
Addition, subtraction, multiplication, and division are all possible mathematical operations. As an illustration, the expression x + y has the terms x and y with an addition operator between them.
In this case, -2 - (-10) will be:
= -2 -(-10)
= -2 + 10
= 8
The value is 8.

First make an equation representing this.
Y= total length
X= the distance from each wall
13 = 2x + 3.5
13 = 2x + 3.5
subtract 3.5 from each side
9.5 = 2x
Divide 2 from each side
X = 4.75 ft
Answer:
61
Step-by-step explanation:
A right angle is 90 degrees meaning you have to subtract 29 from 90, that will equal 61.
