Answer:

a. 7x^2-15=32x

Step-by-step explanation:

a standard form quadratic equation is written as ax^2+bx+c=0

7x^2-15=32x can be rewritten into 7x^2-32x-15=0 by subtracting 32x on both sides.

options b and c don't work  because they include another variable, y

option d is a linear equation, not a quadratic

Do the ratios 42/56 and 56/64 form a proportion?<br> if they do explain your answer
Volgvan
Lets check...

42/56 = 56/64
cross multiply
(56)(56) = (42)(64)
3136 = 2688...(incorrect)...these are not proportional

proportions are nothing but equivalent fractions
42/56 = 3/4
56/64 = 7/8
as u can see, they are not equivalent fractions...so they are not proportional
