Answer:
A = (5s^2t - 9st) (3t + 1)
Step-by-step explanation:
(5s^2 - 9s) (3t^2 + t)
= 15s2t^2 + 5s^2t - 27st^2 - 9st
= 5s2t (3t + 1) - 9st (3t + 1)
= ( 5s^2t - 9st) (3t+1)
Answer:
71
Step-by-step explanation:
This is the answer because:
1) First, add Andy's score and Janet's score in order to know how much they got in total:
- Janet's score: 119 + 96 + 145 = 360
- Andy's score: 127 + 74 + 88 = 289
2) In order to find how much more Janet scored, jus subtract Andy's score from Janet's score:
Therefore, the answer is 71.
Hope this helps! :)
