Pls help me pls thank you sm In advance

x = 10

5x+1= 51

RT=51

Step-by-step explanation:

first, since sides SR and ST are congruent, you can equal them out, to solve for X.

3x-4 = 2x+6

3x-4+4 = 2x + 6 + 4

3x = 2x + 10

3x - 2x = 2x - 2x + 10

x = 10

Then, you plug in for x

5x + 1 =

5(10) +1 = 51

RT= 51

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

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
