Find the value of x for the given value of y. y=x4−7; y=2

y=x4−7; y=2

Y=2 (2)=x.4-7

2+4x-7

4x-7=2  get the variable alone by doing the same thing to both sides

4x=9

4x/4=9/4

y=9/4

x=9/4

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
