To solve the equation LaTeX: 7.5d=2.5d7.5d=2.5d, Lin divides each side by LaTeX: 2.5d2.5d, and Elena subtracts LaTeX: 2.5d2.5d from each side. What is the solution?

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)

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

16.80 times .20= 3.36
