<span>(2m - n)</span>⁷ can be expanded using the binomial theorem or pascal's triangle, but writing out the work is proving to be really difficult. the application of the theorem is pretty complicated and it isn't easy to format in this textbox.
the expansion of this would be 128m⁷ - 448m⁶n + 672m⁵n² - 560m⁴n³ + 280m³n⁴ - 84m²n⁵ + 14mn⁶ - n⁷. let me know if you're genuinely lost on how to find it and i'll give a written explanation a shot, but i'd really, really encourage you to refer back to your notes if you took any in class (or the lesson, if it's an online class) and see if you can find anything which explains the binomial theorem or pascal's triangle. both of those will help you immensely.
<span>What is 5,100,000 in scientific notation?
that would be>></span><span>5.1 x 10^6
HOPE THIS HELPS

4 bagels.....5 people
4/5 = 0.8...so basically, each person gets 0.8 (or 4/5) of a bagel
The area of the square can be found by...
0.75 • 0.75 = .5625
The area of one triangle can be found by...
1/2 • 0.8 • 0.75 = .3
In order to find the total surface area of the figure, you must...
.5625 + 4(.3) = 1.7625
So the answer is D
