If r = 6 and t = 8, which equations are correct? Select all that apply. A. r2 + 4t – 5 = 63
B. –4r – t + 10 = –22
C. –3r + 7t – 9 = –64
D. 2r + t2 + 13 = 41

option A is correct

it is given. r= 6 and t = 8

r^2+ 4t -5 = 63

6*6 + 32 -5 = ? hope it helps

36 +32 - 5 = ??

= 63

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.

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.
