Step-by-step explanation:
From the question we are told that
The length of the treads is 
The length of the risers is 
Generally the slope of the staircase is

=> 
=> 
When multiplying out you get:
x2+4x-3x-12....
so you'd be adding the +4x to the -3x

Answer:
B. 165 degree angle
Step-by-step explanation:
SOLUTION:
To begin with, let's establish the problem as the following:
5 + 7
An effective method to solve this problem would be to convert it into a visual representation in order to obtain a better understanding.
As attached in the diagram above, I have demonstrated the problem visually. The five red circles / dots represent the five in the problem whilst the 7 circles / dots represent the 7 in the problem. Now we must simply count each of the circles / dots to obtain the total number which would be our final answer.
We can also simply use our fingers on our hands to solve the problem by counting 5 on our fingers and then adding 7 or vice versa to obtain the final answer.
FINAL ANSWER:
Hence, through either of these two methods, we obtain the final answer to the problem as follows:
5 + 7 = 12
Hope this helps! :)
