4 km/h because 10-2 because of the 2 km left which =8 then you divide that by 2 to figure out the km per hour which = 4 so 4 km/h
Irrational roots occurs with its conjugate.
Therefore, -√3 is also root of the function.
The answer is -√3.
-Notice that dividing our numbers leaves no remainder:
1,620 ÷ 5 = 324 + 0
-1,620 has all the factors of the number 5
The answer is 48 degrees because you add 42 and 90 and then subtract from 180 (total degrees of a triangle)
You have to turn the denominators the same then whatever you do to the top you do to the bottom the just subtract
