Answer:
Final answer is slope = 0.73
Step-by-step explanation:
Given that an old house has a basement stairway.
Stairway has steps with 7.25 inch vertical risers and 10 inch horizontal treads. Now we need to find about what is the slope of the stairway. Also round the answer to two decimal places.
Now round that value to two decimal places gives 0.73
Hence final answer is slope = 0.73
4. 0.76
5. 0.18
8. 4.48
9. 0.08
12. 3.08
13. 0.45

There are two expressions which do not match with the written descriptions to ist right.
Those are:
1) (4x - 3)^2 - 1: see that the written description does not square the difference of 4x and 3
2) 3(5x^2 + 14x + 7): see that the written description tells that 5 is added to the square ox x, which is not what the expression shows.
The other 4 expressions match with the written descriptions.
So, you can choose those other 4 expressions.
1. 6 1/2
2.4 1/2
3. 9 1/3
4. 9 1/2
5. 9 6/8
6. 6 1/2
(For the adding ones ) I also simplified them.
