Answer:
23
Step-by-step explanation:
64 divided by 2 = 32
(32 - 9)=23
(32+9)= 41
The formula of a volume of a rectangular prism: V = lwh
l - length
w - width
h - height
We have the volume:
![V=6x^3-x^2-2x=x(6x^2-x-2)=x(6x^2+3x-4x-2)\\\\=x[3x(2x+1)-2(2x+1)]=x(2x+1)(3x-2)\\\\Answer:\ \boxed{A.\ Height:3x-2,\ Length:2x+1,\ Width:x}](https://tex.z-dn.net/?f=V%3D6x%5E3-x%5E2-2x%3Dx%286x%5E2-x-2%29%3Dx%286x%5E2%2B3x-4x-2%29%5C%5C%5C%5C%3Dx%5B3x%282x%2B1%29-2%282x%2B1%29%5D%3Dx%282x%2B1%29%283x-2%29%5C%5C%5C%5CAnswer%3A%5C%20%5Cboxed%7BA.%5C%20Height%3A3x-2%2C%5C%20Length%3A2x%2B1%2C%5C%20Width%3Ax%7D)
Answer:
It has 10 three-point questions and 14 five-point questions
Step-by-step explanation:
Substitution (look it up it takes a long time to explain lol)
One way in which to do this problem would involve subtracting 5 from 7 (result: 2) and then subtracting 3/5 from 8/9.
To subtract 3/5 from 8/9, you'd need to find the lowest common denominator (LCD) of 3/5 and 8/9, convert both fractions to have this LCD, and then subtract.
The LCD is (5)(9)=45. Then 8/9 and 3/5 become 40/45 and 27/45.
Subtracting 27/45 from 40/45 results in the fraction 13/45.
Then the full solution is 2 13/45.
You could also do this problem by converting 7 8/9 and 5 3/5 into improper fractions:
71/9 - 28/5. Again, the LCD is 45. Can you rewrite both fractions with 45 as the common denominator and then perform the subtraction?
A negative number in this wouldn't be applicable.
Johnny started out with $2,745 in the beginning, EARNING (This being the key word) interest each year. Therefore, he comes out with $39,974, not being a negative number.
Hope I helped! ^-^
