Answer:
7/5
Step-by-step explanation:
Isolate x
12x-15=6-3x
12x-15+15=6-3x+15 (add fifteen, addition property of equality)
12x=6-3x+15
12x=21-3x (combine like terms)
12x+3x=21-3x+3x (add 3x, addition property of equality)
15x=21 (combine like terms)
15x/15=21/15 (divide by 15, division property of equality)
x=7/5 (simplify)
Answer:
The correct options are;
Line CD is the perpendicular bisector of line AB
Line segment AB is perpendicular to line CD
Line segment AE is congruent to line segment BE
Step-by-step explanation:
From the construction, we have that the radius of circle A is equal to the radius of circle A as the circumference of circle A passes through the center of circle A
Therefore, the construction is the bisection of line segment AB by the construction of the perpendicular bisector CD, from which we have line segment AE is congruent to line segment BE and line segment AB is perpendicular to line CD
