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.

-12 -4x + 3 = -1 what is the value of x
Vinil7 [7]

Answer:

Its -2

Step-by-step explanation:

Let's solve your equation step-by-step.

−12−4x+3=−1

Step 1: Simplify both sides of the equation.

−12−4x+3=−1

−12+−4x+3=−1

(−4x)+(−12+3)=−1(Combine Like Terms)

−4x+−9=−1

−4x−9=−1

Step 2: Add 9 to both sides.

−4x−9+9=−1+9

−4x=8

Step 3: Divide both sides by -4.

−4x

−4

=

8

−4

x=−2
