Hello here is a solution :
x²-10x+25 = 0
x² -2(x)(5)+5² =0
puy <span>identity  : a²-2ab+b² = (a-b)²
(x-5)² = 0
x-5 = 0
the solution is : 5</span>

Let f be the function defined by f(x)=ax2+bx+22x2−8, where a and b are constants. The graph of f has a horizontal asymptote at y
user100 [1]
So since you have a lot of numbers in your paragraph I think you’re gonna have to do some type of equation or are you just have to show your work because You have to show your work to define as what value

Because that is like the right function and a graph is a horizontal asked about so if you were moved its discount Tilly

A weightlifter holds a 1,700 N barbell 1 meter above the ground. One end of a 2-meter-long chain hangs from the center of the ba
masha68 [24]
In physics, work is equal to the product of force and distance, given that the direction of force is the same with the direction of the distance.

W = Fd

The total force is 
F = 1,700 N + 500 N = 2,200 N
Now, if the question is the work needed to lift the barbell from the ground, the distance would be 2 m. Hence, the work would be

W = (2,220 N)(2 m) = 4,400 N·m or 4,400 J
