When adding or subtracting fractions, multiply to get the same denominator (bottom number).

\frac{4}{5}*( \frac{4}{4})  -   \frac{1}{4} * (\frac{5}{5} ) =  \frac{16}{20} -   \frac{5}{20} =  \frac{11}{20}

When multipling two fractions, just multiply straight across, factor diagonally if possible.

\frac{7}{13} * \frac{5}{6} =  \frac{35}{78}

When dividing fractions, flip the second fraction over and multiply.

\frac{13}{17} /  \frac{3}{2} =  \frac{13}{17} *  \frac{2}{3} =  \frac{26}{51}

For the polynomials, you just need to combine like terms.

3x +  4y² + 7x + 6y² = (3x + 7x) + (4y² + 6y²) = 10x + 10y²

You can factor this further but I don't know if its necessary.

= 10(x + y)

Let me know if you have any questions.

What are evidence that the himalayas mountains are still rising​
xeze [42]

Answer:

The Himalayas are still rising by more than 1 cm per year as India continues to move northwards into Asia, which explains the occurrence of shallow focus earthquakes in the region today. However the forces of weathering and erosion are lowering the Himalayas at about the same rate.
