Answer:
a) any amount that isn't 1.5
b) 1.5
c) y = x/4 - 0.5
Answer: Choice C. (x-7)(x-8)
-------------------------------------------------------
Find two numbers that...
* Multiply to 56 (last term)
* Add to -15 (middle coefficient)
Those two numbers are -7 and -8. So that's why x^2-15x+56 factors to (x-7)(x-8)
A^2+b^2=c^2
8^2+6^2=c^2
64+36=c^2
100=c^2
10=c
Final answer: 10 inches
I think its x-5. I think it is i'm not sure tho
