By what factor must you multiply a number in order to triple its square root?

1 answer:

4 0

To solve the problem shown above you must apply the following proccedure:

1. Let's call:

x: a number.
f: the factor.

2. Then, you have:

√fx=3√x

3. You must clear the factor "f" to calculate its value, as below:

√fx=3√x
(√fx)²=(3√x)²
fx=9x
f=9x/x

4. Then, the factor is:

f=9

5. Therefore, b<span>y what factor must you multiply a number in order to triple its square root?

A human factor expert recommends that there be at least 9 square feet of floor space in a college classroom for every student in

jeyben [28]

Answer is very straightforward:
If you got 49 students and require at least 9 square feet of floor space for each of them, the total minimum floor space you need would be: 49 x 9 = 441 square ft.

Hope it helps!

Answer:

2x² + 3x + 4 + (17x + 9) / (x² − 4)

Step-by-step explanation:

Start by setting up the division. Make sure to write all the coefficients, even the zero ones.

x² + 0x − 4 | 2x⁴ + 3x³ − 4x² + 5x − 7

Start by dividing the first term of the dividend (2x⁴) by the first term of the divisor (x²). That's 2x²; it'll be the first term in quotient. Multiply the divisor by 2x²:

2x⁴ + 0x³ − 8x²

Subtract that from the first three terms of the dividend:

3x³ + 4x²

Drop down the next term from the dividend, and start the process all over again.

3x³ + 4x² + 5x

When you finish, the quotient will be 2x² + 3x + 4, and the remainder will be 17x + 9.
