Answer:
It is not equivalent.
Step-by-step explanation:
You have to expand the brackets :
(x-4)(x+3)
= x(x) + x(3) - 4(x) - 4(3)
= x² + 3x - 4x - 12
= x² - x - 12
Therefore, x² - x - 12 / (x-4)(x+3) is not equivalent to x² - 4x - 12.
1. There are 16 ounces in a pound. So you need to divide 48 by 16 to get the number of pounds of chocolate (YUM!) to buy. I get 3 pounds (extra yum!!!).
2.There are 1,000 millilitres in a litre, so 1 millilitre is one thousandth of a litre. The answer is litre.
3. You question is a bit blurry, but I think it says, " (65 divided by 5 ) -4".
In this case, the answer is: divide 65 by 5, then subtract 4.
18 feet = 18/3 yard = 6 yard
6 inches = 1/2 feet = 1/6 yard
Volumen = (6yar)(6yard)(1/6yard) = 6 cubic yard
Cost = 6 cubic yard * $42.00 / cubic yard = $ 252.00
Answer: the first option, 252.00
20.96 × 0.92 = 19.2832 = 19.3
Answer:
1. correct (conversion = x1000)
2. correct (conversion = [divided by] 1000)
3. wrong (conversion should be x100)
4. wrong (conversion should be x1000)
5. correct (conversion = x10)
