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.

This means the maximum height is 50 feet.

The time when this softball reaches this height is between 1 and 2 seconds at 0.8.

Norma-Jean [14]
36j + j = 37j

Explanation.
You could translate this sum into a normal sebtence: I have 36 apples and add 1 apple more.

The sum will then be 36 apples + apple = 37 apples.
Replacing the word (in this explanation 'apple') by a letter learns us 36a + a = 37a

Hence 36j + j = 37j

____ is necessary because researchers in the social sciences almost never have enough resources — time or money — to collect inf
Tanya [424]

Answer:

Sampling is necessary because researchers in the social sciences almost never have enough resources — time or money — to collect information about the entire set of subjects of interest to them.

Step-by-step explanation:

Sampling is done because you usually cannot gather data from the entire population. Even in relatively small populations, the data may be needed urgently, and including everyone in the population in your data collection may take too long.

Kara had a savings account balance of $153 on Monday on Tuesday she has six withdrawals of $15.72 and a deposit of $235.15 what
trasher [3.6K]

Answer:

$293.83

Step-by-step explanation:

She started with $153. The next day she withdrew $15.72 six times, that is $15.72*6 = $94.32

We have to subtract $94.32 from the starting amount, that is $153 - $94.32 = $58.68

After that, she deposited $235.15. We have to add that to the current balance.

Now she has $58.68 + $235.15 = $293.83

Therefore, her account balance after these transactions is $293.83
