10 - 2 (3x + 4) < 11

x > -

Step-by-step explanation:

Given

10 - 2(3x + 4) < 11 ← distribute and simplify left side

10 - 6x - 8 < 11

2 - 6x < 11 ( subtract 2 from both sides )

- 6x < 9

Divide both sides by - 6, reversing the symbol as a result of dividing by a negative quantity.

x > ⇒ x > -

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
