What is the solution of the equation x^2 = 64? a) 8, b) 4, c) +8, d) +4

x = ± 8

Step-by-step explanation:

given x² = 64 ( take the square root of both sides )

= ±

x = ± 8 ← note plus or minus

This is because 8² = 64 and (- 8)² = 64

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

1. perpendicular

2. parallel

3. perpendicular
