Ada is showing her work in simplifying (5.9 - 1.8) - 6.2 + 4.1. in which step did ada make an error? (5 points)
step 1: (5.9 - 1.8) - 6.2 + 4.1
step 2: 5.9 + (-1.8 - 6.2) + 4.1 (associative property)
step 3: 5.9 - 8 + 4.1
step 4: 5.9 + 4.1 - 8 (associative property)
step 5: 10 - 8 = 2

Step 4 is where she made the error.

Step-by-step explanation:

This step is actually known as the commutative property. That property states that we can change the order of numbers as long as we keep the signs and it maintains it's validity.

Step-by-step explanation:

Given

Required

Determine KL

From the given parameters, we understand that K is a point on J and L;

This implies that

Substitute values for JK, KL and JL

Collect Like Terms

To solve for KL, we simply substitute 3 for L in

Hence;
