Assuming it is a square plate, and the area is 49 square cm, each side length should be 7. Length times width equals the area, and 7 times 7 is 49 square cm. Hope this helps!
5 (x+3) = 3*(2x-1)
Solve for x.
5x + 15 = 6x - 3
18 = x

Step-by-step explanation:
What equation?
When we write a line equation in the form

m is the slope of the line, and q is the y-intercept.
Since we want the y-intercept to be -3, our line will look like

In order to fix the slope, remember that two parallel lines have the same slope. So, the slope of the given line y=2x-5 is 2, and since we want a line parallel to this line, our slope will be 2 as well.
Plugging the values, we can finish the equation:

3 + (-4) is the same thing as 3 - 4.
3 - 4 = -1
Hope this helped :)
