Given that CD is the perpendicular bisector of AB, which of the following statements can be used to show that AC=BC?

B. ΔAXC ≅ ΔBXC by SSS, so AC ≅ BC because they are corresponding parts of congruent triangles.

Step-by-step explanation:

From the given diagram, XC is common to ΔAXC and ΔBXC.

And it can be observed that CD divides AB into two equal length segments.

Thus,

AX ≅ BX (bisection property of a line)

AC ≅ BC (congruence property of triangles)

Therefore, the congruence relationship between triangles ΔAXC and ΔBXC would be, Side-Side-Side (SSS) so as to show that AC ≅ BC.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
