4- (+) (-4) is similar to 4+4 by the rule of addition in integers that is if Negative + Negative then Add the number and put the sign of greater number.
<h3>What is integer?</h3>
Zero, a positive natural number, or a negative integer denoted by a minus sign are all examples of integers. The inverse additives of the corresponding positive numbers are the negative numbers. An integer, pronounced "IN-tuh-jer," is a whole number that can be positive, negative, or zero and is not a fraction. Integer examples include: -5, 1, 5, 8, 97, and 3,043. 1.43, 1 3/4, 3.14, and other numbers that are not integers are some examples. Three categories of integers exist: Zero (0) (0) Good integers (Natural numbers) Integer Negatives (Additive inverse of Natural Numbers).
The rules of addition in integers says,
- + - = +
by this,
4-(-4)=8
by concept of addition,
4+4=8

Step-by-step explanation:
Since there are only 4 terms in the sum, it's not too much work to expand it as

Alternatively, we can use the well-known formulas


These sums start at n = 0, so in our given sum we will keep track of the 0-th term separately:

as expected.

The expression which represents the side length of the square which has perimeter of 12x 52 units is 3x+12 units.
<h3>What is the perimeter of a square?</h3>
The measure of the boundary of the sides of a square is called its perimeter. The perimeter of a square is 4 times the side of the square.

Here, (<em>a</em>) is the side of the square.
A square has a perimeter of 12x +52 units. The perimeter of a square is 4 times the side of the square. Thus, the side of this square is,

Thus, the expression which represents the side length of the square which has perimeter of 12x 52 units is 3x+12 units.
