Hey there!

z^2 - 2z + 15

= 15^2 - 2(15) + 15

= 225 - 30 + 15

= 195 + 15

= 210

Therefore, your answer is: 210

Good luck on your assignment and enjoy your day!

Help me please. Very much appreciated​

Answer:

63mm

Step-by-step explanation:

7mm+8mm=15.

15×15=225

12×12=144(area equals base times height) add 225-144=81(here we are using the Pythagoras theory) so you search for the square root of 81 which is 9 meaning the height is 9. since we say area is 1/2base times height we should take 1/2 ×9×12=63.if the answer doesn't match with the answer in your book please tell me right away so that I can try another method thank you
