-5m-9/n+5 + -8m+8/n+5

Mathematics
1 answer:
iren [92.7K]3 years ago
3 0

Answer:

(-13m - 1)/(n + 5).

Step-by-step explanation:

-5m-9/n+5 + -8m+8/n+5

The denominators are the same so we add the numerators:

= (-5m - 9 - 8m + 8 / (n + 5)

= (-13m - 1)/(n + 5).

HELP, Prove: (cos(x))/(sin(x)tan(x))=cot^2x
Mice21 [21]

Answer:

Steps shown below

Step-by-step explanation:

We will simplify this using definitions and identities. Let's start.

\frac{cos(x)}{sin(x)tan(x)}

Using tanx=\frac{sinx}{cosx}, we have:

\frac{cos(x)}{sin(x)\frac{sin(x)}{cos(x)}}\\=\frac{cos^2(x)}{sin^2(x)}

Using cot(x)=\frac{cos(x)}{sin(x)}, we have:

\frac{cos^2(x)}{sin^2(x)}\\=cot^2(x)

Hence, proved.
