Answer:

<u>The correct answer is A. Divide both sides by positive 5</u>

Step-by-step explanation:

Let's solve the equation for finding z and the necessary steps to do it:

5z - 3 = 12

5z = 12 + 3 (Adding 3 at the right side and subtracting 3 at the left side)

5z = 15 (Adding 12 plus 3 at the right side)

5z/5 = 15/5 (Dividing by positive 5 at both sides)

<u>z = 3</u>

<u>The correct answer is A. Divide both sides by positive 5</u>

<h3>What is Congruency?</h3>

Two geometric figures are said to be congruent, or to be in the relation of congruence, if it is possible to superpose one of them on the other so that they coincide throughout.

Given:

AB = 3.5 cm, BC = 2.4 cm, and AC = 4.2 cm

As, ΔABC ≅ ΔHJK

So,

AB = HJ

BC = JK

AC = HK

Thus, HJ= AB = 3.5 cm
