Answer:k=42
Step-by-step explanation:
(5k−3)(9+k)
=(5k+−3)(9+k)
=(5k)(9)+(5k)(k)+(−3)(9)+(−3)(k)
=45k+5k2−27−3k
=5z2+42z−27
=42k
A histogram is a visual display of data.
A histogram is a graphical display of data using bars of different heights. In a histogram, each bar groups numbers into ranges. Taller bars show that more data falls in that range. A histogram displays the shape and spread of continuous sample data.
The length of the side of the square is 11. 3 feet
From the diagram shown, we can see that the square of the length should give the area and is traced down.
<h3>How to determine the length</h3>
It is important tot note that the area of a square is given as;
Area = a²
Where:
a = length of its side
From the diagram, we have that area = 128 square feet
Length of one of the side of the square = square root of it's area
a = √ area
Now, substitute the value of area
a = √ 128
a = 11. 3 feet
From the diagram shown, we can see that the square of the length should give the area.
Thus, the length of the side of the square is 11. 3 feet
