What is the first step in solving this expression? (Use Order of Operations)

30-5(12÷2•6)2

divide 12 by 2

Step-by-step explanation:

According to the order of operations (PEMDAS), you must first solve inside the parenthesis. This means you must now decide whether to solve 12 /2 first or 2 * 6. Because these are division and multiplication, which are equal, you just solve whichever one comes first, or is on the left. That would by 12/2.

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

n=1.75+1.75

step-by-step explanation:

3.5/2=1.75
