Answer:
(m-5) (n-4)
Step-by-step explanation:
mn - 4m - 5n + 20
We will factor by grouping
mn -5n -4m +20
Factor an n out of the first 2 terms and a -4 out of the last 2 terms
n (m-5) -4(m-5)
Now factor out a m-5
(m-5) (n-4)
Answer:

Step-by-step explanation:
From the question we are told that:
Slant Height of Kite 
Angle
Since Emma,The Kite and Andrew forms a right angle triangle
Generally the equation for distance between Andrew from Emma is mathematically given by



Answer:
it will be 7×9 = 63 cuz when you times 4×9 =36 or 5×9 =45
Yes the proportial relationship all increase by the same number so that would be your rate of change
Perimeter of a closed figure is the sum of length of its outline. The perimeter of the consider triangular pool is:
units.
<h3>How to calculate perimeter of a triangular figure?</h3>
Perimeter of a triangle = Sum of lengths of all its 3 sides.
For the given case, we have:
Length of first side(hypotenuse) =
units
Height =
units
Base is of length 
Thus, its perimeter is calculated as:
Perimeter of a triangle = Sum of lengths of all its 3 sides.
Perimeter =
units
Perimeter =
units
Thus,
The perimeter of the consider triangular pool is:
units.
