2 more than the product of 3 and a number is -10.

-4

Step-by-step explanation:

2 more than the product of 3 and a number is -10 can be written as 3x+2=-10.

we can take this equation and solve it, first subtracting 2 from both sides to get 3x=-12.

now we divide both sides by 3 to get x=-4, so the answer is -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
