Answer:
24 (units)
Step-by-step explanation:
Because Quadrilateral EFGH is being dilated by a scale factor of 3/4, this means that each side of E'F'G'H' gets multiplied by 3/4. In this case, we are going to divide by 3/4 to return to the original figure (or multiply by 4/3 since that is the reciprocal)
This means that side HE is 18/(3/4) = 18(4/3) = 72/3 = 24 units
3x+2(x-1)-4
=3x+2x-2-4
=5x-6
Ans: Option A.
Off the top of my head, I cannot think of a circumstance that would make this true. There isn't even 1 exception, especially if you are talking about an incircle and circumcircle for a triangle. They are constructed in entirely different ways which means that they can never be the same thing.
A circumcircle is constructed by using the 3 vertex points of the triangle. An incircle is constructed by using the angle bisectors and perpendiculars. Even with the most regular equiangular triangles are the centers coincident.
False.
Both lines have the same slope, which means they are parallel. They also pass through the same point
. This means they're overlapping so there is infinitely many solutions.<span />
