Correct number but wrong sign Notice that you are multiplying negative by a negative there so the answer must be a positive. Other than that, you have now expanded both brackets. Refer back to the Pythagorean theorem and see what you need to do with the two answers you just got.

Well, technically MINUS 36root5. But yeah you got there. Now continue on with the first part, nearly done.

9. Nope nope nope. You are getting confused.

You had written out.

You worked out what and are because you expanded the required brackets for the side lengths, so just add them together. What you've done right there is which doesn't make sense. Also, don't use the calculator because it will only gives out decimals which are not asked for.

13. Yep! So since the length of the hypotenuse, c, is followed by , you can now find its length, and you will have it in the required form that part a asks for. State the values of a and b once you have done this.

You know that so how can we go about finding c itself? What do we do to both sides? Once you have done this, you can tell what the values of a and b are.
