Which expressions are equivalent to 4d+6+2d4d+6+2d ? choose all answers that apply: choose all answers that apply: (choice a) a 2(3d+3)2(3d+3) (choice b) b 6(d+6)6(d+6) (choice c) c (3d+3)+(3d+3)(3d+3)+(3d+3)\

Options A and C are correct choices.

Step-by-step explanation:

We have been given an expression and we are asked to choose all the equivalent expressions from given choices.

Let us simplify our given expression.

Let us see which of our given choices matches with our answer.

A.

Upon using distributive property we will get,

Therefore, option A is a correct choice.

B.

Upon using distributive property we will get,

Since this expression is not equivalent to our answer, therefore, option B is not a correct choice.

C.

Upon removing parenthesis we will get,

Upon combining like terms we will get,

Therefore, option C is the correct choice.

i dont know sorry

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
