Mathematics
1 answer:
Mamont248 [21]3 years ago
5 0

Answer:

4(x - 3)

Step-by-step explanation:

When you put brackets around a binomial (has 2 parts separated by a plus / - sign), you must take out a common factor from both terms separated by the +  or - sign

A only has the 4 taken away from the x. The answer is not A

B has the 3 removed from the 12, not the x, so B is not the answer.

C that's the answer.

Store display volume of each cube shaped box is 125 cubic inches of the display has six layers of boxes how high is the display
Doss [256]

Answer:

30 inches

Step-by-step explanation:

We know that the formula for calculate the volume of a cube is:

∨=8³

Where "s" is the length of each side.

Since the volume of each cube-shaped box is 125 cubic inches, we can find "s":

125 in³=8³

∛125 in³=8

8=5 in

We know that  the display has six layers of boxes, then , to calculate the height of the display, we can multiply the value of "s" obtained before by 6.

Then:

height= (5 in)(6)=30 in

OverLord2011 [107]
The answer in this question is A, D and E, we might conclude if a random sample of 36 time interval between eruption has a mean longer that 104 minutes, I can conclude that the population means may be greater than 91 and the probability mean must be more that 91, since the probability is low and also the population mean is 91, and this is an example of a typical sampling result.

Yao Xin puts 3/10 liters of potting soil in each pot for planting flowers. She has 17/3 liters of potting soil. How many pots ca
kari74 [83]

For this case defining variables we have:

x: total amount of liters of potting soil.

y: number of liters of potting soil in each pot.

We have then to find the number of pots we use the following expression:

N = \frac{x}{y}

Substituting values we have:

N = \frac{\frac{17}{3}}{\frac{3}{10}}

Rewriting we have:

N = \frac{170}{9}

N = 18.8

Rounding to the previous whole we have:

N = 18

Answer:

Yao Xin can fill 18 pots
