Samuel walked in the Labor Day parade. He walked 3 1/8 miles along the parade route and 2 5/6 miles home. For numbers 3a-3c, fill in each blank. 3a. Rounded to the closest benchmark, Samuel walked about miles on the parade route.

3b. Rounded to the closest benchmark, Samuel walked about miles home.

3c. Samuel walked about miles in all.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
