The length of a rectangle is 15 ft greater than its width. If each dimension is decreased by 2 ft, the area will be decreased by
padilas [110]

Answer:

length = 35ft, width = 20ft

Step-by-step explanation:

We are working with length (L), width (W), and area (A). We are asked to find the 2 dimensions. The question tells us that L = W + 15, so we can express L in terms of W. However, we still don't know what A is. Since we have 2 unknowns, we somehow need to develop 2 equations to get a solvable system.

We can set up the first equation using the relationship between L and W:

W(W+15)=A

We can set up the second equation using the information in the second sentence:

(W-2)(W+13)=A-106

Now we can plug the first equation, already isolated for A, into the second equation and solve for W:

(W-2)(W+13)=W(W+15)-106\\W^2+11W-26=W^2+15W-106\\4W=80\\W=20

A pretty nasty-looking equation actually becomes pretty easy to solve. We know the length is 15ft greater than the width, so if W=20, L=35.

3. (5-0)/(1 -(-8))

5/1+8

5/9

4. (3-3)/(-4 -8)

0/-12

the slope is 0

6. (-2-8)/(1-0.5)

-10/0.5

-20

7. (7-(-1))/ (4-4)

7+1/0
