30(30-x)=540 what is the value of x

x = 12

Step-by-step explanation:

Original equation:

30(30 - x) = 540

Use distributive property

30 · 30 = 900

30 · (-x) = -30x

Plug these values back into the equation

900 - 30x = 540

Subtract 900 from both sides

-30x = -360

Divide both sides by -30

x = 12

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is symmetric about the line y = 120,000.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
