Answer:
Step-by-step explanation:
a. use what's given in the question to write an equation
36x + 12y + 24e (using e as the variable for erasers)
b. 12 is the greatest common factor between the coefficients/ constant so factor it out 
12 (3x + y + 2e) 
12 kits
c. use the factored expression to see how many of each item
3x - 3 pencils
y - 1 crayon
2e - 2 erasers 
 
        
                    
             
        
        
        
M^3 + 9m =
There is a common factor of m.
= m(m^2 + 9)
That is the complete factorization.
m^2 + 9 is a sum of two squares which is not factorable.
Answer: m(m^2 + 9)

Answer:
20, increased, Bianca
Step-by-step explanation:
First one:
He is shown to have travelled 20km in 1 hour, so that's 20km/h.
Second:
The gradient is how steep the curve is, the steeper the faster the person is travelling. Due to the fact Bianca's curve becomes steeper, it shows she is travelling faster. Therefore, her running speed increases.
Third:
Bianca's line hits 50km before Alberto, so therefore she finished first.
Let me know if this makes sense, hope it helped! :D
