(x-4)² + (x-2)² = x²
(x² - 8x + 16 ) + (x² - 4x + 4) = x
2x² -12x + 20 = x
2x²-12x + 20 - x = 0
2x² - 13x + 20 = 0
(2x-5) (x-4) = 0
2x-5 = 0
2x = 5
x = ⁵/₂
x-4 = 0
x = 4
so x₁ = ⁵/₂ , and x₂ = 4
Answer: He rides for 2.5 hours or 2 and a half hours.
Step-by-step explanation:
He needs to complete a trajectory of 22.5 kilometers.
He rides 9 kilometers per hour.
Divide the total by the amount of kilometers that he rides.
Glass A can hold more liquid than glass B
Explanation is
As is asks for water means asking for the volume and the volume for
Cone:- is pie X r^2 X h/3 =134.04
Cylinder:- pie X r^2 X h = 74.4
And remember they gave diameter means * diameter/2 = radius *
58.64 more it holds
Are you trying to figure out what X is? One of the equations equal to 4, and the rest equal to 24.
Answer:
x = 23 degrees
Step-by-step explanation:
sin theta = opposite side/ hypotenuse
sin x= 9/23
Take the arcsin of each side
arcsin( sinx) = arcsin (9/23)
x = arcsin (9/23)
x=23.03568411
Rounding to the nearest degree
x = 23 degrees
