The final expression after combining like terms is 2r + 2.
We are given that;
The expression 8r+7−6r−5
Now,
According to the search results, combining like terms is a common technique for simplifying algebraic expressions. Like terms are terms that have the same variable and exponent.
To combine like terms, simply add or subtract their coefficients and keep the common variable part.
The coefficient is the number that appears in front of the variable.
In given expression, 8r+7−6r−5, there are two like terms: 8r and -6r.
They have the same variable r and exponent .
To combine them, we add their coefficients: 8 + (-6) = 2.
We keep the common variable part r.
So, 8r - 6r = 2r.
The other two terms, 7 and -5, are also like terms.
They are constants with no variables.
To combine them, we add their coefficients: 7 + (-5) = 2.
So, 7 - 5 = 2.
Therefore, by algebra the answer will be 2r + 2.

Assuming that you mean
if we let , the expression becomes
This is an integer if and only if x+4 is a multiple of 4, which in turn happens if and only if x is itself a multiple of 4.
So, the only good options are the multiple of 4, in your case -16.
The solution is, The area is 280.8 inches² of one triangular section.
Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.
here, we have,
given that,
If the base of the panel is 31.2 inches and the height is 18 inches,
we know that,
Area of triangle = base × height ÷ 2
here, we have,
b = 31.2
h= 18
so, we get,
A = 18 × 31.2 ÷ 2
we know,
18 × 31.2 ÷ 2 = 280.8
so, A = 280.8
The area is 280.8 inches².
Hence, The solution is, The area is 280.8 inches² of one triangular section.

Solve the equation:
5x + 65 = 25
What is the value of x
Answer: -8
Step-by-step explanation:
Answer:
x = -8
Step-by-step explanation:
If you multiply -8 by 5 you get -40. Then if you add 65 to -40 you get 25.
Hope this helps.
