Simplify the square root to 60 times 4. Do the square root 4 then it is 2 times the square root of 60. You can simplify 60 to 4 times 15. the square root of 4 is 2 and multiply 2 times 2 which is 4. Then you final answer is 4 times the square root of 15. Hope this helps!

Step-by-step explanation:

Find the prime factorization of 240.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
