What is the expanded form of 4(7x+3)

Step-by-step explanation:

4×7x+4×3=28x+12 I don't know what you mean with expanded form but i hope it helped

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 correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem

hope this
