In the question, the given expression is
And we have to find the equivalent expression to the given expression .
First we remove the parenthesis
Now we combine the like terms, and here like terms are z and z, therefore on combining , we will get
And that's the required equivalent expression .
You cut the cookie in 4 parts and give them 3 pieces
Consider the point where the hexagons meet the positive half of the y axis.
The inner hexagon meets the axis at , whereas the outer hexagon meets the axis at
So, we're looking for a dilation constant such that
So, solving by k we have
360 is the answer that you need
The answer is: 90° .
