<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.
Answer: y - x = 1
Step-by-step explanation: Note : for two lines to be parallel, then they have the same slope.
i.e the slope is 1
Using y - y1 = m ( x-x1) to find the equation of the line
⇒ y - 2 = 1 (x - 1)
y - 2 = x - 1
y - x = -1 +2
y - x = 1
it could also be written in slope intercept form as y = x + 1
Area of a rectangle = length x width
Answer:
slope = - 1
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (2, 8) and (x₂, y₂ ) = (6, 4)
m = 
= 
= - 1
