The degree and direction of rotation that takes ΔQRS to ΔQ'R'S' is:
45 degrees; anticlockwise direction.
<h3>What is rotation in math?</h3>
The transformation by rotation refers to the movement of a shape or point in a circular path about a fixed point.
When the shape moves in an anticlockwise direction, it means that It is going in the opposite way as the hands of a clock do.

just kidding its 396.5
hope this helped
For 1- 4 all you have to do is multiply the numbers.
An easier way to write the same equation out would be to add multiplication signs. For example:
1. -2*3 is the same as (-2)(3)
When there are two parentheses next to each other without a sign in between, that means multiplication.
6-9 can also all be converted to be a whole number, which is what it want you to do.
11 and 12 is where you need to multiply and then add or subtract after you multiply.
Also, for 13 and 14, both the fractions can be converted to be a whole number, so you should turn them into whole numbers first and your life will be a lot easier.
And 15 is also the same thing as 11 and 12.
Extra Help: When you have two negative numbers, the answer will end being a positive and when there are two positive it will remain a positive, and a negative and positive number will be a negative.
