Answer:
the answer is d. 4x²+x-6
Step-by-step explanation:
In order to combine the fractions, they need to have the same denominator.
So, multiply each of their numerators by the denominator they need to be equivalent.
This would look like this:
3x/x+3 --> 3x(x)/x(x+3) ---simplify this as--> 3x²/x(x+3)
x-2/x --> (x-2)(x+3)/x(x+3) ---simplify this as --> x²+x - 6/x(x+3)
3x 3x(x) x-2 (x-2)(x+3)
----- ---> ----- and -------- ---> ---------
x+3 x(x+3) x x(x+3)
now that both fractions have the same denominator, we can add their numerators.
3x² + x²+x-6 = 4x²+x -6
This should now look like this:
4x²+x -6
-------------
x(x+3)

Answer: 55,425.2 cm3
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a hemisphere = 2/3 π radius^3
Replacing with values given and solving for V (volume)
V = 2/3 π (29.8) ^3 = 55,425.2 cm3
In conclusion, the volume of the hemisphere is 55,425.2 cubic centimeters.
Feel free to ask for more if needed or if you did not understand something.
Answer:
because it is a triangle we square the lenght and equate to the other side,and square all the other side
X²=20²+10²
X=√20²+10²
=22.36m
Mean is the average. Add the numbers together and divide the the quantity of numbers.
5 + 11 + 14 + 10 + 8 + 6 = 54
54 / 6 = 9
Mean = 9
