Answer:
The least common multiple is 2y^2 - 50.
Step-by-step explanation:
Least common multiple means the lowest thing you can multiply them both to. For example, the LCM of 2 and 4 is 2, because 2*2 = 4 and 4*1 = 4.
First, factor 2y^2 - 50.
2 (y^2 - 25)
2 (y - 5)(y + 5)
Looks like if we wanted to get 2y^2 - 50 starting with y - 5, we'd have to multiply it by 2(y + 5).
2y^2 - 50 * 1 = 2y^2 - 50
y - 5 * 2(y + 5) = 2y^2 - 50
<u>So their least common multiple is 2y^2 - 50.</u>
Answer:
C = 18.85
Step-by-step explanation:
The formula for the circumference of a circle is C = 2πr
R = radius
C = 2π(3)
C = 18.84955592
From the given condition we can conclude that the radius of the cylinders are different.
Step-by-step explanation:
Given,
The height of a right cylinder and an oblique cylinder is same.
Volume of these two cylinder is different.
Let us take,
Radius of right cylinder = r
Radius of oblique cylinder = R
Height = h
Volume of right cylinder = πr²h
Volume of oblique cylinder=πR²h
Formula
If the height and the radius of a right cylinder and an oblique cylinder is same, their volume is also same
Thai is = πr²h
Here,
As the volume is different we can conclude that
The radius is not same.
Answer:
ok
Step-by-step explanation:
12√18-6√20-3√50-8√45
<em>*Break each radical up into the product of a radical of a perfect square and a second radical*</em>
12(√9*√2)-6(√4*√5)-3(√25*√2)-8(√9*√5)
<em>*Simplify the radicals*</em>
12(3√2)-6(2√5)-3(5√2)-8(3√5)
<em>*Distribute*</em>
36√2-12√5-15√2-24√5
<em>*Combine like terms</em>*
21√2-36√5
Hope this helps!!
