Answer:
20x - 8
Step-by-step explanation:
Since we have the length and height of the rectangle we just multiply each by 2. This is because the length is the same on both sides and the height is too. The equation would look like this:
(5x-4 + 5x -4) + (5x +5x) = 10x -8 + 10 x = 20x -8
<u>Answer:</u>

<u>Step-by-step explanation:</u>
We are given the following two points and we are to find the equation of the line which passes through them:
(-3, 1) and (0,0)
Slope = 
Substituting the given values and the slope in the standard form of the equation of a line to find the y intercept:



So the equation of the line is 
Answer:
(x , y) = (2 , 1)
Step-by-step explanation:
// Solve equation [1] for the variable x
[1] x = -4y + 6
// Plug this in for variable x in equation [2]
[2] -(-4y+6) - 2y = -4
[2] 2y = 2
// Solve equation [2] for the variable y
[2] 2y = 2
[2] y = 1
// By now we know this much :
x = -4y+6
y = 1
// Use the y value to solve for x
x = -4(1)+6 = 2
