Answer:

12(4+3)

Step-by-step explanation:

Factor out all of the problems.

Starting with 4(12+4)

This means (4*12)+(4*4)

48+16 is the answer to this

this isn't 48 + 36

12(4+3) is next

12*4 = 48

12*3 = 36

48+36 = 48 + 36

Therefore 12(4+3) is your answer

hope that helps!

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.

A sink has two faucets: one for hot water and one for cold water. The sink can be filled by a cold water faucet in 3 minutes. If

iragen [17]

Answer: $6\ minutes$

Step-by-step explanation:

You can use the following formula:

$\frac{T}{A}+\frac{T}{B}=1$

You can say that "T" is the time (in minutes) for both faucets working together, "A" is the time (in minutes) for cold water faucet working alone and "B" is the time (in minutes) for hot water faucet working alone.

Based on the data given in the exercise, you can identify that:

$T=2\\A=3$

Therefore, substituting these values into the formula and solving for "B", you get that this is:

$\frac{2}{3}+\frac{2}{B}=1\\\\\frac{2}{B}=1-\frac{2}{3}\\\\\frac{2}{B}=\frac{1}{3}\\\\2=\frac{1}{3}B\\\\2*3=B\\\\B=6$

There are two different loci that cause white coat color in horses. One locus is the albino locus found in all mammals. Albinism

julsineya [31]

Answer: 6/12 are white, 3/12 are colored and 3/12 are albino.

Step-by-step explanation: If the horses are white and their parents are ccww (albino) and CCWw (white horse), according to Mendel's premises, they both must be CcWw, since the crossing provides one C from one parent and other c from the other parent, one W and the other w. Using Mendel's chess and the principle of independent segregation, the crossing between CcWw results in the following fenotypical ratio:

1/16 CCWW (lethal)

2/16 CCWw (white)

2/16 CcWW (lethal)

4/16 CcWw (white)

1/16 CCww (normal)

2/16 Ccww (normal)

2/16 ccWw (albino)

1/16 ccWW (lethal)

1/16 ccww (albino)

Excluding the 4 individuals that have the lethal locus, we have 6/12 that are white (2/12 + 4/12) and 3/12 (1/12 + 2/12) that are colored. Also, there are 3/12 of albino individuals as well.
