ANSWER

EXPLANATION
The outermost square tile has side length,

The area of a square is given by;

We substitite the given expression for the side length into the formula to obtain,


We expand using the distributive property to obtain;

This gives us:


The last choice is correct.
Answer:
Given:
x-y=-4
2x+y=4
Step-by-step explanation:
x-y=-4
2x+y=4
add both the equation, we get
⇒ x-y=-4
2x+y=4
⇒3x=-4+4
⇒3x=0
⇒x=0
∴ to find the value of y, put the value of x in any one equation
⇒x-y=-4
⇒0-y=-4
⇒-y=-4
⇒y=4
∴ x=0, y=4
Answer:
x=0
Step-by-step explanation:
2x+4(-8x)=0
2x+-32x=0
-30x=0
x=0
Answer:
The required expression is
Step-by-step explanation:
Difference of two minus three = 2-3
Quotient of b divided by the difference of two minus three is
Therefore, the required expression is

42 because x is equal to its corresponding side
