Ooo! I love these! Ok so your IQR is C or D. I might have my calculations wrong if so. Sorry!
x + y when x = 6 and y = 2
6 + 2 = 8
when x = 12 and y = 20
= 37
when m = 12 and n = 3
= 24
Six times x
6x
Six increased by x
6 + x
The sum of x and y
x + y
Answer:
4(2x+7) which is equal to 8x+28
dot on top of earth = plane position at the time of observation (right one when 37°, left one 53°)
