Help With My Test - PLEASE!!?

Question

I need help with the following questions. I am terrible at math and I want to check my answers. I NEED a good grade on this test!!
1) If you subtract 13 times a number from 3 times its square, the result is 10. Translate into an equations and solve.

2)A photograph is 7in long & 5in wide. It is surrounded by a border of uniform width. If the area of the border is 64 sq in, what is the width of the border?

3) Factor this completely: a*2 + 14ab + 45b*2
(the * means the next number is the exponent)

4) Facotr completely: x*3 + 64

Factor completely: 5x*4 + 18x*2 + 9

THANK YOU FOR ANY AND ALL HELP!!

Don't you have better things to do then smart off to people that are asking for help? get a dang life. I do pay attention in class......math is my weakness. Are you going to tell me you are perfect at everything??? I doubt it. I am a mature married adult that is going back to school to get another degree.......where do you get off judging me for having a problem in math. Find somewhere else to be a jerk to people.

It is a take home work sheet...BUT.....if we score high enough on it we can use it to replace a lower test grade.
I just want to check my work....if I know my answers aren't correct...I can atleast see the correct one and figure out where I messed up. We HAVE TO show our work....so I will still have to figure out where my mistakes are on my own.

Answer 1

3x^2 -13x + 10

x^2+6x-16 =0

(a +9b)(a+5b)

sum of 2 cubes

(5x^2 + 3 )(x^2 +3)

Answer 2

Ok.... a test???? no...no...im not helping you....because its a test that would be 'cheating'! If it was a project/worksheet than I would help you!
