Which of the following is the quotient of the rational

Mathematics
1 answer:
Alona [7]3 years ago
5 0

Answer:

It is A

Step-by-step explanation:

We you divide, you multiply the reporical of the second term for example when I say

2 \div 3

I also mean

2 \times  \frac{1}{3}

So it is the same concept but in more complicated way

\frac{4x}{2x - 1}  \div  \frac{3x + 2}{x + 5}

You flip the second term

\frac{4x}{2x - 1}   \times  \frac{x + 5}{3x + 2}

Then you multiply the numerator and you will get

4x {}^{2}  + 20x

Which is found in A,but you will need to multiply the denominator in case if the choices have the same numerator

The denominator. Equals to

6x ^{2}  + x - 2

Create a quadratic trinomial with zeros equal to 4 and 5
Ilya [14]

Answer:

x^2 - 9x + 20

Step-by-step explanation:

(x - 4)(x - 5) (have to do the opposite for it to be positive)

FOIL method: X x X = x^2

-5 x X = -5x

-4 x X = -4x

x^2 - 5x - 4x + 20

-5 - 4 = -9 so...

x^2 - 9x +20 is the answer

NeX [460]

Answer:

40%= 4.4
