Help what is it i cant do whatever peganroym therom thing is

13.4

Step-by-step explanation:

use a^2+b^2=c^2

longest side=18 so c=18

other leg= 144

plug it in: 12^2+b^2=18^2

144+b^2=324

144+b^2=324-144

180 square root= 13.4

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50
