Hey!
so for A, you just distribute the 3x
the answer would be 3x^2 - 12x

For B what you want to do is the same thing but dont forget to distribute the negative as well!
Your answer would be -2x^3 - 3x^2

Hope this helps!

also since you are multiplying, here is a tip. When you multiply and you have 2 x's that are going to be multiplied like x times x, you want to add the exponent!

x = 42 / 0.96
x = 43.75

The Westside Bakery uses 310 pounds of flour to make 1,000 loaves of bread. Each loaf
DanielleElmas [232]

Answer:

310 / 1000 = 0.31 pounds

Step-by-step explanation:

When dividing by a number that is 1 less 0 than how many digits the number has, we can move the decimal point the number of times zero is repeated at the end of the number.

1000 has 3 zeroes, so we move the decimal point 3 moves to the left.

So, we do this:

After 0 moves: 310

After 1 move: 31.0

After 2 moves: 3.10

After 3 moves = 0.310

0.310 is the same as 0.31

Therefore, 0.31 pounds of flour are in each loaf.

Answer:

a) 300 + 80h = x

b) $780

Step-by-step explanation:

So, the original cost is $300, plus an additional $80 times the number of hours rented.

h will represent the number of hours rented

x will represent our total cost (use whatever variable your teacher expects :))

300 + 80h = x

This is our equation. Now, we want to find the cost for 6 hours. Substitute 6 in for h.

300 + 80(6) = x        Solve for x.

 300 + 480 = x

            780 = x        This means the total cost for 6 hours will be $780.

Hope this helps :)

NOTE: I noticed in part a, it referred to a "dunking booth". I solved this problem as if that was a typo and they were referring to the jumper.
