Step-by-step explanation:
Tip: When finding the circumference of a circle, just multiply the radius by 2!
Hope I get my brainliest even tho I couldn't get all of it!
I would say A. I hope I am right. I dunno if it would be A. or C. But I think A would be the better pick.
Answer: n⁴+10n²x+25x²
Step-by-step explanation:
I don;t know how I can use the binomial squares pattern on Brainly, but I can definitely guide you through the problem.
(n²+5x)² [rewrite this from the squared]
(n²+5x)(n²+5x) [use FOIL to expand]
n⁴+5n²x+5n²x+25x² [combine like terms]
n⁴+10n²x+25x²
The answer is B.) one of the numbers is negative.
So if you take the example...
-3 x -7 = 21
then we know that they equal a positive.
21 ÷ -3 = -7
Step-by-step explanation:
![(4x^2-x+6)-(3x^2+5x-8)=4x^2-x+6-3x^2-5x+8](https://tex.z-dn.net/?f=%284x%5E2-x%2B6%29-%283x%5E2%2B5x-8%29%3D4x%5E2-x%2B6-3x%5E2-5x%2B8)
By simplifying the right side of the equation, we come up with
, or D
