I need help/answers for these questions it will be a huge faveur../
1-Simplify:
a: 3x(5x-2) -x (x(squared)-7) -x
b: 5w-3(squared)-2+2w
c: 8(x+3)-2(x-1)
2-Solve:
a: 8x-7=5(x+4)
b: 8-2x=5
c: 3x-5=7
d: 7(3-p)=9-4p
3-First three numbers in a sequence are 1, 2 and 4 exlapin why the fourth term would be 7 or 8..
4-Factorise the expiression
3x(squared)-15x
5-Work out and leave answers as fraction
2/3+3/5+7/4
2 6/7 + 1 3/4
2 1/2 + 1 3/4

"I must not fear. Fear is the mind killer. Fear is the little death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone I will turn the inner eye to see its path. Where the fear has gone there will be nothing. Only I will remain." - The Litany Against Fear, "Dune" by Frank Herbert |

3 divides 15 evenly
x divides x^2 evenly
