Answer:
The length is 20, and the width is 15.
Step-by-step explanation:
You have to write an expression to represent this situation. w can be the width, and the length can be 2w-10. To fnd the area, you multiply these together. w(2w-10) is 2w^2 -10w. From there, 15 is the only value of w that satisfies the equation, so w=15. Substitute 15 into your expression for lngth, and 2(15)-10 is 30-10 is 20, so the length is 20.
First of all, subtract the amount the boots costed from the total price.
109.95-29.99
= 79.96
Now you have the price of the 4 sandals.
To find the price of 1 pair, divide this total by 4
79.96 / 4
= 19.99 $ for one pair of sandals!
