Functions can only have 1 value of 'x'.

Option A is not a function because it has two -5's

Option B is not a function because it has two -2's.

Option C is a function.

Option D is not a function because it has two 6's.

I really need help on both but if you can only answer one that's perfectly fine!
Fofino [41]

Answer:

110, 15%

Step-by-step explanation:

So for the first problem, recall that there is 100%. 12% of the answers on a test were missed.

There are 125 questions on the test.

To find the answer, what we can do it multiply 125 by 100%-12%

So 125*88%

THis can be looked at as:

125*.88

=

110

So we know the first answer is 110, now lets move onto the next one.

There a few ways of diong this, we could do 100%- each of the answers, and then multiply that by 2760 and see if we get 2400, but there is an easier way of doign this.

Take your 2760, and divide it by 2400. This will get you 1.15. So 2400 is increases by .15. This is equal to an increase of 15%.

There is a catch to this one however, when you divide 2400 by 2760, which should get you 85%, it gets you 86%. This would be 14%. So the answer seems to be 15%, but if not, its none of the above.

So answers:

110 and 15%(or none of the above)

Hope this helps! I am sorry about the bottom answer though, but 15% makes the most sense to me.

The dimensions for a rectangular prism are x + 3 for the length, x + 2 for the width, and x for the height. What is the volume o
lisabon 2012 [21]

Answer:

the answer will be x^3 + 2x^2 + 9x

Step-by-step explanation:

as :

volume = l* w* h

= X * (X + 2) * (X + 3)

= X ^ 2 + 2 X (X + 3)

= x ^2 (X + 3) + 2x (X + 3)

= x^3 + 3x +2x ^2 + 6x

= x^3 + 2x^2 + 9x

I need the solution and the work for it... for each of the multiple choices.
Vlad1618 [11]

For this case we have the following equation:

x ^ 3 = 375

We must find the value of "x":

We apply cube root on both sides of the equation to eliminate the exponent:

x = \sqrt [3] {375}

We can write 375 as 5 ^ 3 * 3

So:

x = \sqrt [3] {5 ^ 3 * 3}\\x = 5 \sqrt [3] {3}

Then, the correct options are:

x = \sqrt [3] {375}\\x = 5 \sqrt [3] {3}

Answer:

Option A and B
