Answer:
f(g(x))=16x^2+6x-4
Step-by-step explanation:
f(g(x))=4(2x)^2 +3(2x)-4
f(g(x))=16x^2+6x-4
Answer: $32.70
Step-by-step explanation:
Total amount spent on Video game rentals:
= Number of video game rentals * rental price of video game
= 5 * 2.10
= $10.50
Total amount spent on DVD rentals:
= Number of DVD rentals * rental price of DVD
= 6 * 3.70
= $22.20
Total spent on both:
= 10.50 + 22.20
= $32.70

Tyrell worked on
16 - 2(4 + 3x)
what do brackets mean ? they mean that this operation has to be done before everything else in the expression.
as this contains a variable, we cannot fully calculate it, true, but we need to keep this in mind and always treat the content of the brackets as one package.
so, whatever I do from the outside with one part of that package, I have to do also with all the other parts of that package.
so, the multiplication with -2 has to happen with both : 4 and 3x. not just with 4.
therefore, the correct simplification looks like
16 - 8 - 6x
8 - 6x or -6x + 8
Amelia multiplied correctly, but then made a mistake summing things up
10x - 3(4x + 1)
10x - 12x - 3
10x - 12x = -2x
I can't mix the pure constant -3 into the factors of x. that would be like the famous mixing of apples and oranges.
so, the result is
-2x - 3
You would do 20 • 3=60 and the you would add 20 • 1/5=4 so, your total is 64in.
