Which expressions are equivalent to 4d+6+2d4d+6+2d ? Choose all answers that apply: Choose all answers that apply: (Choice A) A

Sliva [168]

Answer:

Options A and C are correct choices.

Step-by-step explanation:

We have been given an expression $4d+6+2d$ and we are asked to choose all the equivalent expressions from given choices.

Let us simplify our given expression.

$4d+6+2d=(4d+2d)+6$

$4d+6+2d=6d+6$

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

A. $2(3d+3)$

Upon using distributive property $a(b+c)=a*b+a*c$ we will get,

$2*3d+2*3$

$6d+6$

Therefore, option A is a correct choice.

B. $6(d+6)$

Upon using distributive property $a(b+c)=a*b+a*c$ we will get,

$6*d+6*6$

$6d+36$

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

C. $(3d+3)+(3d+3)$

Upon removing parenthesis we will get,

$3d+3+3d+3$

Upon combining like terms we will get,

$(3d+3d)+(3+3)$

$6d+6$

Therefore, option C is the correct choice.

lisov135 [29]

The estimated lengths are 12in. and 5 in. This would be an estimated difference of 7in.

The estimated difference is going to be higher than the actual difference because in rounding 11.7 to 12, you are losing .30in, but in rounding down 5.25 to 5, you are actually gaining .75in.

The ACTUAL difference is 6.45in
