Use substitution to solve the following system of equations.
d + e - f = -3
e = f + d + 7
f = 2e - 6
a. d = 3, e = -4, f = 2
b. d = -4, e = 3, f = 2
c. d = -2, e = 4, f = -5
d. d = -5, e = 4, f = 2

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
