Mathematics
1 answer:
Volgvan4 years ago
3 0

Answer:

3 inches

Step-by-step explanation:

(14+2x) × (15+2x) = 2(14×15)

210 +30x +28x + 4x² = 420

4x² + 58x - 210 = 0

2x² + 29x - 105 = 0

2x² + 35x - 6x - 105 = 0

x(2x + 35) - 3(2x + 35) = 0

(x - 3)(2x + 35) = 0

x = 3, -35/2(not possible)

What is the answer?....
Anon25 [30]

Answer:

third answer choice:  11

Step-by-step explanation:

f(x) = 4x + 3.  Now if we let x = 2, we get f(2) = 4(2) + 3 = 11.

This '11' becomes the input to function g:

g(x) = x - 2, so g(11) = 11 - 2, or 9.

Thus, g(f(x)) = 9

A skier is trying to decide whether or not to buy a season ski pass. A daily pass costs ​$79. A season ski pass costs ​$300. The
PolarNik [594]

Answer:

4

Step-by-step explanation:

With either pass you have to add $20 per day, so you can ignore that

Assuming he goes "x" days to sky you can calculate the days he has to go to equal $300.

300 = 79x

x = 300/79 = 3.8 days

If he goes 4 days to sky it costs 316, so in that case its cheaper to buy the season pass

You don't have to answer them all but help me out !!
Mandarinka [93]

Answer:

1. 10n

2. 3x^2z^2

3. 2(9n^3 - 3n^2 + 3n - 1)

4. (Put the same thing)

5. There are no common factors so it is completely factored out.

Step-by-step explanation:

For 1, you gotta find the gcf of the numbers and the variables. So, the common factor of 90, 70, 70, and -80 is 10. Nothing else greater than 10 divides these numbers. For the variables, only "n" is the GCF, as there is one "n" and all the other numbers have n^2 and etc.

For 2, same thing, you have to find the gcf for the numbers and the variables.

3. same thing ;-; (gcf is 2 btw, nothing divides the variables because 2 has no "n".

4. theres nothing that divides the numbers or the variables. So, the gcf is just 1.

A cubical dice is thrown two times, find the probability that the outcomes is 5 in first throw and odd number in second throw.​
trapecia [35]

All the numbers present in cubical dice = 6

  • ( 1 , 2 , 3 , 4 , 5 ,6 ) <u>Total Outcomes = 6</u>

<u>Probability = Favorable outcomes / Total number of outcomes </u>

  • Probability that 5 will come in first throw :-

<u>Favorable Outcomes = 1 </u>

<u>Favorable Outcomes = 1 Probability = 1/6</u>

  • Probability that an odd number will come in second throw :-

<u>Favorable Outcomes = 3</u>

<u>Probability = 3/6 ; 1/2</u>
