Answer:
x^2-x-5
Step-by-step explanation:
1. expand the square
(+1)(+1)−3(+2)
2. distribute
(+1)+1(+1)−3(+2)
3. distribute
^2++1(+1)−3(+2)
4. multiply by 1
^2+++1−3(+2)
5. combine like terms
^2+2+1−3(+2)
6. distribute
^2+2+1−3−6
7. subtract the numbers
^2+2−5−3
8. combine like terms
^2−−5
9. gg you are done
^2−−5
Answer:
Yes it is is 392.9 m^3
Step-by-step explanation:
Volume of cylinder is π*r^2*h, π times radius squared times height.
Since the diameter is 5.2, the radius is 2.6 (half of it). 2.6^2 = 6.76, and the height is 18.5, 6.76*18.5 = 125.06. Multiply it by pi to get 392.887577258, round it to 392.9, The volume is 392.9 cubic meters.
Step-by-step explanation:
There is no diagram, please update question.
6x^2 / 45x = 6x / 45
6x / 45 = 2x / 15
The number in scientific notation is 4.901 * 10^7
<h3>How to express the number in scientific notation?</h3>
The number is given as:
Number = 49,010,000
A number in scientific notation is represented as:
a * 10^b
Where a is any number between 1 and 10.
So, we have:
Number = 4.901 * 10^7
Hence, the number in scientific notation is 4.901 * 10^7
