Answer:
Nope the answer would be -6.5
Answer:
8(4-x)
Step-by-step explanation:
You're multiplying the difference of four and a number (4-x) by eight (8). So writing as an expression would look like 8(4-x).
You're looking for the volume of the prism. The dead giveaway there is that you're looking for "cubic" measurement. Cubic measures are indicators that the volume is being determined, just like "square feet" or inches, etc indicates area is being determined. The volume for this prism is found by multiplying the length times the width times the height. In decimal form, 45×30×40=54,000. But that is in cubic inches and we want cubic feet. So we will use dimensional analysis to convert that. Setting up the DA looks like this, keeping in mind that there are 12 cubic inches in 1 cubic foot:

. The label of cubic inches cancels out leaving us with cubic feet, and doing the division there gives us 54,000/(12*12*12) which is 31.25 cubic feet.
Answer:
$245,000
Step-by-step explanation:
Let the intial cost = x




We can simplify it a bit
oh wait,
remember taht x^0=1, no matter what x is
we see the whole thing is to the zero power
the whole thing is equal to 1
doesn't matter what x or y is
the whole thing evaluates to 1
