Which quadratic equation is equivalent to (x2 - 1)2 - 11(x2 - 1) + 24 = 0? U2 - 114 + 24 = 0 where u = (x2 - 1)
O (422 - 11(42) + 24 where u =
(x² - 1)
O u2 + 1 -110 + 24 = 0 where u =
(u2 – 1)2 - 11(u2 – 1) + 24 where u = (x2 - 1)
(x² - 1)​

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!

$15 each

$45/3 children= $15 each
