Step-by-step explanation:
It’s a total of 15miles pereimtere have a good day :)
The first two rows of coefficients are identical, so by inspection, the determinant is 0.
Start by, 60/30= then 2*20= 40 so 40 bottles for 20 runners.
Answer:
The correct answer will be X = 4
Step-by-step explanation:
Using Pythagoras
AB^2 + BC^2 = AC^2
2^2 + (2√3)^2 = AC^2
4 + (4*3) = AC^2
4+12 = AC ^ 2
AC ^2 = 16
AC = √16 = 4
