Hal makes an error when determining the difference quotient of f(x) = x2 + 11x + 2. His work is shown.

StartFraction ( (x + h) squared + 11 (x + h) + 2) minus (x squared + 11 x + 2) Over h EndFraction. StartFraction x squared + h squared + 11 x + 11 h + 2 minus x squared minus 11 x minus 2 Over h EndFraction. StartFraction h squared + 11 h Over h EndFraction. h + 11.

Which statement describes the error?

He did not expand (x + h)2 correctly.
He did not combine like terms correctly.
He should have subtracted f(x) – f(x + h), not
f(x + h) – f(x).
He should have added f(x + h) + f(x), not subtracted
f(x + h) – f(x).

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!
