What is the first step when rewriting y = 6x2 + 18x + 14 in the form y = a(x – h)2 + k? a.16 must be factored from 18x + 14
b. x must be factored from 6x2 + 18x
c.6 must be factored from 6x2 + 14
d.6 must be factored from 6x2 + 18x

step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
