A dog named Bella has a rectangular bed that is 2 feet wide and 4 feet long. A larger dog, Kahuna, has a rectangular bed which is 5X feet wider and 9X feet longer than Bella’s bed

10 feet wide and 36 feet long

Step-by-step explanation:

5 x 2= 10 wide

4 x 9= 36 long

what is the starting amount? the question is not clear sorry.

step-by-step explanation:

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
