Answer:
1) replace only the left-hand side of one equation with the sum/difference of both equations
2) no
Step-by-step explanation:
i just did this problem lol
The answer is false from what i know
If you type that equation into Desmos graphing calc it’ll solve it for you
Answer:
The sum is the solution when you add two (or more) numbers together. So, the expression is (x+4)+(x-8).

Answer:
180x - x²
Step-by-step explanation:
Since the yard has 360 yd. of fencing, hence the perimeter of Rick's lumberyard has 360 yd.
Given that the yard is x yards long. Let y represent the width of the yard. Hence:
Perimeter of the yard = 2(length + width) = 2(x + y)
Substituting:
360 = 2(x + y)
180 = x + y
y = 180 - x
Therefore the width of the yard is (180 - x) yard.
The area of the yard is the product of the length and the width, hence:
Area (A) = length * width
A = x * (180 - x)
A = 180x - x²
