She need 3 bags since the area of the triangle is base x height /2
Area 20*6=120
120/2=60
60/20= 3 since each bag covers 20m^2
Answer:
15,36,39
Step-by-step explanation:
A right triangle will satisfy Pythagoras Theorem:
c² = a² + b²; where c is the longest side.
6/2*3 / 3(3)
First simplify the numerator: 6/2*3 = 3*3 = 9
Next simplify the denominator: 3(3) = 3*3 = 9
So you have 9/9, which equals 1.
The 3rd answer is correct.
1) 18
2) 4
3) 27
4) 9
5) x=8
6) x=6
