I need help please I need it
SashulF [63]

Step-by-step explanation:

It asks you to choose values for w, the width, and evaluate the equation for each. It describes the constraint "the perimeter of 20 units" The perimeter of a rectangle is the length of all the lines of a regtangle.

Or

2L + 2W = 20 reduce this to simplest for by dividing both sides by 2;

L + W = 10, so the length plus the width is 10. Rearrange it to be W = 10 - L. Values of W can range from 1 to 9. Now sove for a few points in the function.

f(W) = 10W - W^2

3; 10(3) - 3^2 = 30 - 9 = 21.

If we look at the constraint, L = 10 - W, when the width is 3 the length must be 7. The area of a rectangle is L x W, 3 x 7 = 21. That checks against the function.

Solve for additional points.

4; 10(4) - 4^2 = 40 - 16 = 24.

If W is 4 the L is 6 and 4 x 6 = 24

If you have a job that earns $120 in 2 days, how much would you earn in 6 days? Use a chart to show the proportion of earnings f
zepelin [54]
To figure this out, we need to use fractional proportions.

Currently, we have $120, the amount earned, and 2 days, the current rate.
Our fraction for this is: 120 / 2 = x / 6, x being the amount earned in 6 days.

Let's use a little technique to help us answer faster.

With our current money earned, 120, and our current days, 2, we can divide 120 by 2 to find out how many we earned in 1 day.

120 / 2 = 60.

We earned $60 per day.

With this formula, 60d, d being the amount of days, we can solve quicker.

We are solving for 6 days, so multiply $60 by 6 days.

60 x 6 = 360

Your proportion is : 

120/2 : 360/6

I hope this helps!
