Answer:

x= -8 x=2

Step-by-step explanation:

x^2 +6x-6= 10

Subtract 10 from each side

x^2 +6x-6-10= 10-10

x^2 +6x-16 = 0

What 2 number multiply to -16 and add to 6

8 * -2 = -16

8 -2 = 6

(x+8) (x-2)=0

Using the zero product property

x+8=0 x-2=0

x= -8 x=2

Maxi is trying to stack books on a shelf that is 18 inches tall. If the books are each 4/5 inch thick, how many can she stack?

kari74 [83]

I believe it should be 22½ or 22 books

You would need to divide 18 and ⅘

18 ÷ ⅘ = 22½

I hope this helps, even though I’m not totally sure :)
