Which equation has the solution n = 11? 7n − 8 = 62

8n + 6 = 102

3n + 12 = 45

5n − 20 = 25

3n+12=45

Step-by-step explanation:

Because if you take 2 and put it in the place of n 32+12 =45 and take 45 and divide it by 12 and you will get 11.

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
