Answer:
divide the figure into two parts.
area of triangle = 1/2×base×height
area of triangle = 1/2×3×3
area pf triangle = 4.5 units²
area of square = side²
area of square = 3²
area of square = 9unit²
Answer:
k=4
Step-by-step explanation:
-The constant of proportionality is defined as the ratio between two directly proportional variables.
-Given that B=4f
#The constant of proportionality is calculated as:
- the equation can be written in the form y=kx,
where y varies directly with x and k is the constant of variation:

Hence, B varies directly with f with a constant of proportionality k=4
Answer:
The factored form is:

Step-by-step explanation:
The given expression is:

The Greatest Common Factor is 4:
We factor the GCF to get

We rewrite the expression within the parenthesis as difference of two squares.

Recall that: a²-b²=(a-b)(a+b)
This implies that

Yes, reduce 104/56 by 8, you get 13/7.
Answer:
Option 1) 10 sides
Step-by-step explanation:
We are given a regular polygon. The sum of interior angles measure upto 1440 degrees.
Since it is a regular polygon, it satisfies the following properties:
- All the sides are equal.
- All interior angle have same measure.
Let the regular polygon have n sides.
Then, the sum of interior angle is given by:

Putting the values, we get,

Thus, there are 10 sides. The regular polygon is a regular decagon.
