Answer:
The length is 30 (which you aready said) and the width is 40
Step-by-step explanation:
1200/30=40
(another way)
120/30=4 (multiply each side by ten)
So,
The standard form is:
y = mx + b
First, we find "m," the slope. Subtract the y-coordinates from each other. Do likewise with the x-coordinates.
2 - -3 = 5
2 - 0 = 2
Slope = 5/2

Now, we can substitute the second solution into this equation for x and y and solve for "b."


Now we have our complete equation.
Polynomial:
an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable or variables
