Eight less than the product of three and a number is twenty-two

The number is 10.

Step-by-step explanation:

Given that if we product 3 with a number and then subtract eight from it then we will get twenty-two.

So, if the number is x, then by the condition given we can write  

3x - 8 = 22

This is a linear equation of single variable x, so it will have a single solution.

Now, 3x - 8 = 22

⇒ 3x = 30

⇒ x = 10 (Answer)

i just took the test, the correct answer is .. 31.5 in.

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
