Step-by-step explanation:
55 / 3 = 18.333.
Since it is a decimal, we round up to the nearest whole number.
It will take at least 19 battles to level up.
Answer:
A.
Step-by-step explanation:
you have to find the discriminant
b²-4ac for each equation
if discriminant < 0 no real solutions because will be negative under the squareroot whhan you try to find the roots
if discriminant = 0 there is only one solution
if discriminant > 0 two real solutions
for your given problems
A. discriminant =(-2)²-4*2*15 will be negative
Let's find the value of x
Since the sum of internal angles of a triangle is 180°
therefore,
Using the cosine double angle formula,
(Note I took the positive case since terminates in the first quadrant)
Using the Pythagorean identity,
(Note I took the positive case since terminates in the first quadrant)
