Find the value of X 11x-2 19x+3 9x+1 PLEASE LOOK AT PICTURE

x=4

Step-by-step explanation:

1) first write it down --> 11x-2+9x+1=19x+3

2) then combine like terms on the left side of the equation. --> 20x-1=19x+3

3) Then subract 19x on both sides --> x-1=3

4) After add 1 to both sides --> x=4

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

may i see the picture? it would a lot, xox
