235 total miles minus the 55 miles youve already driven = 180 miles left to drive
divide that 180 by the 60mph and its 3 hours left to drivs
The answer would be A and C.
Hope this helps!<3
The right triangle is also Isosceles. It has two equal angles of 45°.
(hypotenuse)² = 2S²
4 = 2S² => S = √2
Therefore B is the correct answer.
Put it in you cal it helps
Discriminant = b^2 - 4ac
a = 4
b = 16
c = 16
16^2 - 4(4 x 16)
256 - (4x64)
256 - 256 = 0
Therefore it only has one root
