<em>Greetings from Brasil...</em>
Here, just apply the Metric Relationships to the Rectangle Triangle
AB² = BC · BD
10² = 16 · X
16X = 100
X = 100/16
<em>simplify</em>
100 ÷ 4 = 25
16 ÷ 4 = 4
X = 25/4
<h3>X = 6.25</h3>
Group of students = 18/18 (100%)
Boys = 9/18 (50%)
Boys with brown eyes = 4/18 (idk :p)
It's 4/18 because:
Brown eyed boys make out the 4/9 of the boys, and boys make out the half of the whole class. So the easiest way was to double 9 and get x/18. (Sorry for my bad English..)
Answer:
An expression for the perimeter of the square as a product using the expression for the length of one side .
Step-by-step explanation:
Given : The perimeter of a square is represented by the expression feet.
To find : Write an expression for the perimeter of the square as a product using the expression for the length of one side ?
Solution :
We know that the perimeter of the square is 4 times the side of square.
The perimeter of a square is represented by the expression feet.
Divide the expression by 4,
So, the perimeter is also written as with length of side
Therefore, an expression for the perimeter of the square as a product using the expression for the length of one side .
The answer is there what u need help with?
