Very simple problem!

25 = 3x + x + 7

find the variable

25 = 3x + x + 7

25 = 4x + 7

4x + 7 = 25

4x - 7  = -7

4x        18

----- =  ------           (Divide)

4          4

x =

Sorry, I'm not the best at using these tools but that is the correct answer.

if im undersanding the question correctly, its organized from 10

step-by-step explanation:

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
