@iGreen.

Answer 2

If you FOIL \[x \times x=x^2\]\[x \times -5=-5x\]\[x \times 5=5x\]\[-5 \times 5=-25\]
So you'll get \[x^2-5x+5x-25\]

Answer 3

so its A?

Answer 5

Not A. because you have the -5x and 5x. Since they both have an x to the 1 power, you can combine those. So -5x+5x=?

Answer 6

d or c?

Answer 7
