(7x^3 – 4x^2) + (2x^3 – 4x^2)
Add 2x^3 to 7x^3
(9x^3 - 4x^2) + (-4x^2)
Add -4x^2 to -4x^2. This would be the same as subtracting 4x^2 from -4x^2
Final Answer: 9x^3 - 8x^2
*The answer cannot be broken down anymore. It's in it's simplest form.
21 is nearly 25% of 80, so my estimate is 25%
I believe that it is 2,000 because you multiply it by 2 three times.
The answer is C .2417 because you add them then divide by 7
True. There are two ways to solve this; one, a shortcut , which is when you add each of them up and they are greater than each other (9+4= 13, which is greater than 11), or you could also use the Pythagorean theorem to solve the problem; the formula is
a squared + b squared= c squared
