<h3>How to simplify an expression?</h3>
The expression have to be simplified by combining the like terms.
Like terms are terms whose variables (and their exponents such as the 2 in y²) are the same.
Therefore,
8x +7 - 2x + y
The like terms are 8x and 2x . Therefore, lets combine it.

Answer:
24 m^2
Step-by-step explanation:
There are two areas to consider here: first, the area of the wall, and second, the area of the window. We answer this question by finding these two areas and subtracting the area of the window from the area of the wall.
Wall area: (4 m)(7 m) = 28 m^2
Window area: (2 m)(2 m) = 4 m^2
Net area of wall, to be covered in brick:
28 m^2 - 4 m^2 = 24 m^2

Answer:
5x=13.5
Step-by-step explanation:
Well, we know that 1x=2.7. So, if we want 5x we need to multiply 2.7*5 becuase 1x=2.7, so 5x=2.7*5.
Multiply. 2.7*5=13.5
So, 5x=13.5.
