What is the difference of r+2/r+4 and 3/r+1?

I assume you mean:

(r+2)/(r+4)-3/(r+1) we need a common denominator of (r+1)(r+4)

[(r+2)(r+1)-3(r+4)]/(r^2+5r+4)

(r^2+3r+2-3r-12)/(r^2+5r+4)

(r^2-10)/(r^2+5r+4)

now you could factor out the answer if you wanted to...

((r+√10)(r-√10))/((r+1)(r+4))

What is the value of p in the question below. 10x9/2x4= px 5

ycow [4]

Answer:

p = 5

Step-by-step explanation:

We have that:

$\frac{x^{a}}{x^{b}} = x^{a-b}$

So

$\frac{x^{9}}{x^{4}} = x^{9-4} = x^{5}$

10/2 = 5

Then

$\frac{10x^{9}}{2x^{4}} = 5x^{9-4} = 5x^{5}$

Finding p:

$5x^{5} = px^{5}$

$p = \frac{5x^{5}}{x^{5}}$

$p = 5$
