Answer:
Step-by-step explanation:
Let's call B at the base of the triangle and call h at the height of the triangle. Then we know that:
The height of a triangle is 5 cm shorter than its base. This means that:
.
The area of the triangle is 25 cm²
By definition the area of a triangle is:
For this triangle we know that 
and . We substitute these values in the equation and solve for B.
Now we use the quadratic formula to solve the equation.
For an equation of the form 
the quadratic formula is:
In this case note that: 
Then:
The solutions are:
For this problem we take the positive solution.
Now we substitute the value of B in the equation to find the height h

140 divided by 14 is 10. So x is 10. And Y is 140. 140 divided by y (1) =140
Answer:
18 pages per hour.
If you do 36 (the pages/amount) divided by 2 (The time), you get 18.
To double check, when you do 90 (The pages/amount) divided by 5 ( The time), then you get 18 again.
Therefore the answer is 18 pages per hour.
