Need help please. Thanks <3
Please send the solution in detail
Please show your complete solutions. Thankyou!
1) find all the answers as soon as possible.
You must solve both the questions here.Otherwise skip it pls. Request u Don't solve only one. If u do, I will dislike it. Don't do it if u don't want to solve both questions. Skip it if u don't want to solve both.
Please answer all and show solutions/ illustrations.
I cant get it right, both answers below are incorrect. I need(a) and (b).
pls help ASAP & pls draw a picture/representation, thanks!
Please give me both answers otherwise leave it... Remember give me both answers.. Thank you
Can you write this out. I dont understand how this is supposed to be solved
Please provide typed answer. I NEED TYPED ANSWERS. Thank you.
Please hand-draw it on paper if possible. Thank you!
