D. He dilated the dimensions by different factors!
A=3 b=5 c=2
x = -b +-sq root(b^2 -4*a*c) / 2a
x = [-5 +-sq root(5^2 -4*3*2)] / 6
x = [-5 +-sq root(25 -24)]/6
x = [-5 +- 1] /6
x1 = -1
x2 = -4/6 = -2/3 = -.66666666666666

Answer:
a) <u>7</u>b+<u>6</u>=<u>97</u>
b)b=13
Step-by-step explanation:
Total cost = $97
Cost of each book = $7
Cost of shipping =$6
Therefore ,
Cost of the total no. of books+ Cost of shipping = Total Cost
=>7b+6= 97 <------- Answer to part(a)
=>7b=97-6
=>7b=91
=>b=13
No. of books = 13 <--------- Part (b)
