It is not written in scientific notation because there should be a decimal in 44 in order to be correct. It should be 4.4 x 10 ^8
Answer: 4x3 - 24x2 + 22x -6
Step-by-step explanation:
(4x - 2)(x2 - 5x + 3)
(4x3 - 20x2 + 12x)
+ (-4x2 + 10x - 6)
4x3 - 24x2 + 22x -6
Answer:
41 minutes
Step-by-step explanation:
We are given;
Time spent on homework = 90 minutes
Time spent reading = 2/3 hours = 2/3 × 60 minutes = 40 minutes
Time spent making lunch = 540 seconds = 540/60 minutes = 9 minutes
We want to find how many more minutes Roberto spent doing homework than he did reading and making his lunch.
Thus;
Time spent on reading and making lunch = 40 + 9 = 49 minutes
Hence, the word "how many more" means we will subtract 49 from 90.
So, "how many more minutes" = 90 - 49 = 41 minutes
