Answer:
They Would be if they Have a pattern from left to right such as +2 or -5.
Step-by-step explanation:
If an example is counting up from 15 to 31 and 0 to 8 the pattern is Adding Two. So if the numbers decrease or increase in a certain way, then you can find out what it is and thn bam, your answer to the question.
C. 3w + 8 - w = 4w - 2(w - 4)
(3w - w) + 8 = 4w - 2w -2(-4)
2w + 8 = 2w + 8
Either of two angles whose sum is 90 degrees
3x+y=17
=> 3x=17-y
Again, x+3y=-1
=> 3y= -1-x
now, 3x+3y= (17-y)+(-1-x)
= 17-y-1-x
= 16-x-y
