Answer: m²-mn
Explanation: multiply the letter outside the brackets by everything inside the brackets, so, m×m = m² and m×n = mn, altogether it is m²-mn.
The answer is 16. Spinning an even number and flipping tails
Answer:
V = 15.7*x^2 + 125.6*x + 251.2 I'd use this as an answer, but it depends how you have been told to treat pi. This answer is also possible.
V = 5*pi*x^2 + 40*pi*x + 80*pi
I can't really tell you which one to use.
Step-by-step explanation:
Givens
V=pi*r^2 * h
pi = 3.14
r = (x + 4)
h = 5
Solution
V = pi * (x + 4)^2 * 5
V = pi * (x^2 + 8x + 16)*5
V = pi * (5x^2 + 40x + 80) Now the question is what to do with pi.
V = 5*pi*x^2 + 40*pi*x + 80*pi
That one possible answer. The other is to give pi a value
V = 15.7*x^2 + 125.6*x + 251.2
Well if you split 1/4 in half then that will give 1/8. You must also split 0.25 in half which gives 0.125
Now you can multiply that by 5 which gives 5/8. But also the fraction
Now we know that 5/8 = 0.625
Step-by-step explanation:
There can be more than one:
Here are some:
206/8x
515/20x
1030/40x
