Answer:
x5-2x3+2x2-8x+4
Step-by-step explanation:
multiplying them we get
x5-4x3+2x2+2x3-8x+4
= x5-2x3+2x2-8x+4

Answer:
x = -1
Step-by-step explanation:
<u>Step 1: Combine like terms on the right side
</u>
6 - 8x = 7x - 9x + 12
6 - 8x = -2x + 12
<u>Step 2: Add 8x to both sides
</u>
6 - 8x + 8x = -2x + 12 + 8x
6 = 6x + 12
<u>Step 3: Subtract 12 from both sides
</u>
6 - 12 = 6x + 12 - 12
-6 = 6x
<u>Step 4: Divide both sides by 6
</u>
-6 / 6 = 6x / 6
-1 = x
Answer: x = -1
Answer:
126
Step-by-step explanation:
To calculate this, we need to assume at least one white marble will be picked... so let's take it out of the bag. Then we need to pick 4 more marbles... it's just then a combination calculation.
How many marbles is there in total? 4 + 3 + 2 + 1 = 10
We do just as if we had removed one white marble from the bag... so that leaves 9 in the bag.
We have to pick 4 out of those 9.... so, it's simple combination calculation:
C(9,4) = 9! / (4! (9--4)!) = 9! / (4! 5!) = 126
Some of those grabs will have 2 white marbles... but we're assured that there are 126 ways to combine the 10 marbles so there's at least one white in the 5 picked (since we forced it in our calculations).
The 3 variable in this question are the item, their prices, and the quality. using these three variable we get the equation
P1x + P2y + P3z
as we are counting 5 days worth of ice cream sales, that expression must be multiplied by 5 before it is complete
5(P1x + P2y + P3z)
that is your expression
:)
