Answer:
8c - 7r + 10p - 20e
Step-by-step explanation:
(20c + 15r + 75p + 50e) - (12c + 22r + 65p + 70e)
(subtract like terms) (aka. 20c - 12c, 15r - 22r, 75p - 65p, 50e - 70e)
8c - 7r + 10p - 20e
Answer:
Number 2
Step-by-step explanation:
Answer:
|-3| - |6| = 9
| 6 - -3| = | 6+3| = 9
Step-by-step explanation:
The distance between points is given by
d = sqrt( (x2 -x1) ^2 + (y2-y1) ^2 )
Since the y coordinates are the same
d = sqrt( (x2 -x1) ^2 )
d = sqrt( x2-x1)^2)
Or the distance between the two points
The distance between them is 9 units
|-3| - |6| = 9
| 6 - -3| = | 6+3| = 9
