Answer:
21y² +34 yx + 8x²
Step-by-step explanation:
Area of a rectangle is given by L×W where L is length, and W is width
Given L=3y+4x
W=7y+2x
Area= (3y+4x) × (7y+2x)
3y(7y+2x) + 4x(7y+2x)
21y² + 6yx +28yx+8x²
21y² +34 yx + 8x²
I've uploaded a photo with the answer because it's too hard to do this out on the computer.
<span>the equation of the line y = 1/3 (x+2)
to solve for x , multiply the whole eqaution by 3, which results to:
</span>[y = 1/3 (x + 2)] 3
3y = x + 2
then transpose the 2 to the other side of the equation
3y - 2 = x
x = 3y - 2
so the answer of remmi is correct. i hope this can help you, feel free to ask for clarifications
