Answer:
A, D
Step-by-step explanation:
Sub the x and y values into the equation. The x value is the first number in the coordinate, and the y value is the second number.
If the left side is equal to the right side, it is a solution.
Example:
4x-5y=24
4(-9)-5(-12)=24
-36+60=24
24=24
Remember: if the left side does not equal the right side, it is not a solution.
if the length is 8ft and the width is (7+x) then the area would be 56+8x, if x is unknown.
Answer:
49 is equal to 7 times 7
Step-by-step explanation:
The factors of an expression are the quotients of the expression
The model that represents the factors of 
is the product of x -1 and x - 8
<h3>How to determine the model</h3>
The expression is given as:
Expand the expression
Factorize the expression
Factor out x - 8
Hence, the model that represents the factors of is the product of x -1 and x - 8
