Here is an equation is true for all values of x: 5(x+2)=5x+10. elena saw this equation and says she can tell 20(x+2)+31=4(5x+10)+31 is also true for any value of x. how can she tell ? explain your reasoning

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

i can't solve unless i know what the line is

step-by-step explanation:

welcome to/p>

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
