26 + 18 = 44 and 18 + 34 = 52.
Step-by-step explanation:
hopefully this helps! i don't kno if they covered this subject in school though for me.
You can apply the Pythagorean theorem:
a^2 + b^2 = c^2
c is the longest side of the triangle
2.2^2 + 4.2^2 = 6.7^2
4.84 + 17.64 = 44.89
22.48 =/= 44.89
That is not a right triangle
Answer:
There are 24 boys and 4 teachers.
Step-by-step explanation:
To get 18, you multiply 3 by 6. To get 24, you multiply 4 by 6.
You add 18 and 24 together to get 42, which is double 21 and there are 2 teachers for every 21 students
The area is about 91 units^2
The perimeter is about 39 units
