Factor the linear expression: 15x + 6

  3(5x +2)

Step-by-step explanation:

15 and 6 have a common factor of 3.

  15x +6 = 3(5x +2)

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

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
