Someone help me with the two math problems

Mathematics

BigorU [14]2 years ago

Answer:

13. x=0, x= -4

14. NO EXCLUDED VALUE

Step-by-step explanation:

13. set the denominator to equal to 0 = x^2 + 4x = 0

factor the expression x × (x + 4) = 0

separate into possible cases = x = 0 and x = -4

state the excluded value = x = 0 and x = -4

14. set the denominators equal to 9 = x^2 +81 = 0

the statement is false for any value if x = x € ℝ

2m-6=4m+8 how do i answer this in algebraic proof
Nonamiya [84]

Answer:

m=-7

Step-by-step explanation:

You begin with the equation:

2m-6=4m+8

The first step of this would be to subtract 2m from both sides. This is the subtraction property of equality.

-6=2m+8

The next step would be to subtract 8 from both sides. This is the subtraction property of equality.

-14=2m

Next, divide both sides by 2. This is the division property of equality.

-7=m

The final step would be the symmetric property of equality.

m=-7

Therefore your proof would have the steps:

subtraction property of equality

subtraction property of equality

division property of equality

symmetric property of equality

The cylinders are similar the volume of the larger cylinder is 9648 cubic inches what is the volume of the smaller cylinder
olga nikolaevna [1]
To find the volume of the smaller cylinder you will need to determine the scale factor by comparing the 2 cylinders. The scale factor is 1:2. This means that each dimension will be divided by 2 when going from the larger to the smaller figure.

Because volume is a three dimensional measurement, you need to divide 9648 by 2, three times.

9648/2=4824
4824/2=2412
2412/2=1206 cubic inches

The volume of the smaller container is 1206 cubic inches.
