Answer:
The explanation of this question is given below in the explanation section
Step-by-step explanation:
The data is given in form of length and width.
Then, we need to convert it into improper fraction.
As you know that, the improper fraction is a fraction where the numerator (top number) is larger than the denominator (bottom number).
So, we converted it into improper fraction i.e.
Improper fraction= lenght/width
Then we reduce the fraction into lowest form and shown in ratio as depicted in attached picture with this solution.
Answer:
a(a + 3b)
Step-by-step explanation:
a² + 2ab + ab
a² + 3ab
a(a + 3b)
Answer:
The length of the focal width of the parabola is 1.
Step-by-step explanation:
Suppose we have a parabola with the following equation:

The centre is at point
.
The length of the focal width is of |4p|.
In this question:
We want to place in the general format. So


Comparing, we have that 4p = 1. So the length of the focal width of the parabola is 1.
