According to my calculations the answer should be 750
7 Expand and simplify where necessary
a 3(4p + 1)
b -6(3T + 5)
ç 4(3x – 2y) + 4(x + 4y)
d 7(2m - 3) - 9(y - 1)
Summary
pretty simple dont suck

ROC= change in y/change in x
3/-1
The rate of change is -3
Answer:
The answer is 4z^2 + 7z
Step-by-step explanation:
7z + 4z^2 +6 - 6
So, just combine like term which is 6 - 6 = 0
So, the remaining is 4z^2 + 7z that cannot be simplified anymore
Either 175.25 ( 175.2 + 0.1/2) or 175.15 ( 175.2 - 0.1/2) ----------> Range. 175.15 < weight < 175.25
