Simplify 6 to the fifth power over 7 cubed all raised to the second power

I’m really confused and need to learn this

Talia grouped the terms and factored out the gcf of the groups of the polynomial 15x2 – 3x – 20x + 4. her work is shown below. (15x2 – 3x) + (–20x + 4) 3x(5x – 1) + 4(–5x + 1) talia noticed that she does not have a common factor. what should she do?

Which of the following points is a solution to the system of equations shown? y - x = -1 x + y = -5
