Find x=, if x+4=7 now!

x=3

Step-by-step explanation:

x+4=7

Subtract 4 from both sides

x=3

Or

x+4=7

Insert numbers to see which makes the expression true

1+4=7

Nope

2+4=7

Nope

3+4=7

Yep

x=3

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
