Answer:
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.
It equals 2, explanation 1+1=2
since they're similair then similair sides will be proportional
CB is similair to EF
\frac{6}{8}86 = \frac{3}{4}43
same thing if you try with the hypotenuse AB similair to DE
\frac{13.5}{18}1813.5 = \frac{3}{4}43
So, if you multiply r (DF) by 3/4 you will get the similair side AC
rx 3/4=12
r= 12÷ 3/4
<h3>r=16.</h3>
