An expression is shown below:

square root of 50 plus square root of 2

which statement is true about the expression?

it is irrational and equal to 2 multiplied by the square root of 13.

it is irrational and equal to 6 multiplied by the square root of 2.

it is rational and equal to 2. it is rational and equal to 6.

B) It is an irrational number and equal to 6 multiplied by the square root of 2.

Step-by-step explanation:

Given:   √50 + √2

We can write √50 = √25*√2

= 5√2      [√25 = 5]

Therefore, √50 + √2 = 5√2 +√2

= 6√2

B) It is an irrational number and equal to 6 multiplied by the square root of 2.

Hope this will helpful.

Thank you.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
