You need to use Pythagorean theorem.
A^2+b^2=c^2
X^2+32^2=40^2
X^2+1024=1600

Nina [5.8K]
Three hours after the bus starts out, it's 150 miles ahead of the truck. Then the truck starts out, and it gains (65-50)=15 miles on the bus every hour. If neither of them ever stops for anything, the truck will catch up to the bus in ( 150/15 ) = 10 hours. . . . (The hint is useless.)

Mrrafil [7]

Given:

Book club A charges $20 for membership and $2 per book rental.

Book club B charges $10 for membership and $3 per book rental.

To find:

The number of books for which the cost be the same at both book clubs.

Solution:

Let x be the number of books.

Book club A charges $20 for membership and $2 per book rental. So, the total cost is

C_1=20+2x             ...(i)

Book club B charges $10 for membership and $3 per book rental. So, the total cost is

C_2=10+3x            ...(ii)

Equating (i) and (ii), we get

10+3x=20+2x

3x-2x=20-10

x=10

The total cost is

C_1=20+2(10)

C_1=20+20

C_1=40

Therefore, the total cost at both book clubs are same for 10 rental books and that cost is $40.
