Which two operations are needed to write the expression that represents “four times the difference of a number and three”? multiplication and subtraction division and subtraction multiplication and addition division and addition

the answer is multiplication and subtraction.   four times (multiplication) and the difference (subtraction) of a number and three.

step-by-step explanation:

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
