Answer:
c
Step-by-step explanation:
2(6y − 3) = 20 + 6y
Use the distributive property, which states a(b - c) = ab - ac
We should get:
2*6y - 2*3 = 20 + 6y
Which can be simplified to:
12y - 6 = 20 + 6y
That means the mistake was in step 2. The student didn't multiply the numbers and instead added the numbers.
Your answer is: <span>Step 2: 12y-6=20+6y</span>
Answer:
Enlargement transformation
Step-by-step explanation:
A dilation is a transformation which produces an image of the same shape as the original, but may/may not be of the same size. A dilation could be an enlargement, reduction or a congruence.
The following rule applies(given the scale factor k)
- If k > 1, there is an enlargement.
- If 0 < k < 1, there is a reduction.
- If k = 1, there is a congruence.
therefore, since k=6/5=1.2>1, there is an enlargement transformation
