Find the value of b and c
show work!

b(3x-2x+c) = 9 - 6x+15

b=3

c=5

Step-by-step explanation:

b(3x^{2}-2x+c) = 9x^{2} - 6x+15

Distribute

3b x^2 -6x +bc = 9x^2 -6x +15

Each term must be equal

3bx^2 = 9x^2

3b = 9

Divide by 3

3b/3 = 9/3

b =3

bc = 15

3c =15

Divide by 3

3c/3 = 15/3

c =5

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!
