Solution:
we are given that
In a class, every student knows French or German (or both).
15 students know French, and 17 students know German.
Suppose there are x student who knows both French and German.
Then Total number of student in the class will be 
But to guess the largest possible number of student in the class we can assume x=0
Hence the largest Possible number of Student in the class=32
Answer:
the length of the third side (the hypotenuse) is 7
Step-by-step explanation:
Solve this by using the Pythagorean Theorem:
(2√10)² + 3² = (hypotenuse)²
Then (hypotenuse) = √(40 + 9) = √49 = 7
Answer:
-5
Step-by-step explanation:
if r was 7 it would be 7-12 so 7 - 12 is -5
The area of the trapezoid is the amount of space on it, and the value of the area is 16.5 square cm
<h3>How to determine the area?</h3>
The given parameters are:
Parallel sides = 3cm and 8 cm
Height = 3cm
The area is then calculated using:
Area = 0.5 * (Sum of parallel sides) * Height
So, we have:
Area = 0.5 * (3 + 8) * 3
Evaluate
Area = 16.5
Hence, the area of the trapezoid is 16.5 square cm
