Factor completely x2 + 64.

(x + 8)(x − 8)
Prime
(x + 8)(x + 8)
(x − 8)(x − 8)

Prime

Step-by-step explanation:

x^2 + 64 cannot be factored any further

Option A: (x + 8)(x − 8)

Step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
