We can use the distributive property to simplify this expression.
I split this up into different parts--it helps me visualize better.
To begin, "-2m(m + n - 4)" becomes "-2m^2 - 2mn + 8m"
Then, "5(-2m + 2n)" becomes "-10m + 10n"
Finally, "n(m + 4n - 5)" becomes "mn + 4n^2 -n"
We can then simplify even further by combining like terms. The final expression is: C
Hope this helps!
Answer:
f(x) = 2x – 3
f(0) = 2(0) – 3 = -3
f(1) = 2(1) – 3 = 2 – 3 = -1
(f(0) + f(1))/2 = (-3 - 1)/2 = -4/2 (f(0) + f(1))/2 = - 2
The answer us 25/4
the third option
He paid 20 + 13, so 33 for the pumpkins and now you need to add the tax.
To compute the TAX ONLY, you would multiply 0.07 ( which is 7%) by 33, and you get $2.31. So the final cost with tax would be $33+ $2.31= $35.31
An easier way to compute total cost with the tax included would be to multiply $33 by 1.07, and you get the same answer as above, $35.31.
Do you see the difference? Some questions will ask for the amount of tax only, others will ask for the amount paid including tax.
I don't think that's possible.
