Answer:

$\frac{{x}^{2} - 9}{{x}^{2} - 16}$

Step-by-step explanation:

$[\frac{(x - 3)(2x + 1)}{(x - 4)(x + 5)}][\frac{(x + 3)(x + 5)}{(x + 4)(2x + 1)}] = \frac{(x - 3)(x + 3)}{(x - 4)(x + 4)} = \frac{{x}^{2} - 9}{{x}^{2} - 16}$

In order to figure this out, you have to factor every single trinomial in the denominators and numerators. By doing this, you will arrive at your answer alot swifter.

I am joyous to assist you anytime.

Solve for x: 3 over 4 x + 5 over 8 = 4x

vaieri [72.5K]

Step-by-step explanation:

3/4x + 5/8 = 4x/1

5/8 = 4x/1 - 3/4x

5/8 = 16x^2 - 3/4x

5/8 = 4x - 3/1

5/8 = 4x - 3

Cross multiply

8(4x - 3) = 5

32x - 24 = 5

32x = 5 + 24

32x = 29

X = 29/32

So the sequence begins as {4, 7, ... }
