I NEED HELP ITS ALGEBRA I HOPE THE PICTURE DOESNT TURN BLANK AGAIN

14 is answer c and 15 is b but I'm not expert

Step-by-step explanation:

for 14 plug area into the area equation and solve for r. most difficult part here is you have to know to take the square root to eliminate the square exponent. then plug r into the circumference equation to find answer. for 15 you know length is 1/3 of h so let's say l=h/3 and plug in all our values here so find h. 187.5=2.5*h*h/3 so 75=h*h/3 let's multiply it out to say h^2/3 and then multiply 3 over so 225=h^2 and again with the sqrt so h=15

step-by-step explanation:

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
