Answer:
1. Not rhombus
2. Rhombus
3. Rhombus
Step-by-step explanation:
The little lines you see represent the size. So if you see one line on all sides, its a rhombus. If you see 1 line on one side, 2 lines on two sides, and 3 on the last side, it is not a rhombus.
Look for the lines.

Andrew is 33 years old. One third of 33 is 11:
33 × 1/3
= 33/3
= 11
Now, the distance in years between 11 and 33 can be calculated accordingly:
33 - 11 = 22
Therefore, 22 years ago Betty was 1/3 of Andrew's age. Which means Betty hadn't been born yet.
Question:
Which is equivalent to after it has been simplified completely?
Answer:
Step-by-step explanation:
Given
Required
Simplify
We start by splitting the square root
Replace 180 with 36 * 5
Further split the square roots
Replace power of x; 11 with 10 + 1
From laws of indices;
So, we have
Further split the square roots
From laws of indices;
So, we have
Rearrange Expression
From laws of indices;
So, we have
<em>The expression can no longer be simplified</em>
Hence, is equivalent to
