Answer:
P=16+2x
Step-by-step explanation:
The formula for finding the perimeter of a rectangle is P=2l+2w.
Plug the length of 8 and the width of x into the formula.
You'll get P=2(8)+2(x).
Multiply. 2•8=16 and 2•x=2x.
Your expression is P=16+2x.
I hope this helps.
Ahh this is a good hard question, I hope someone comes along and helps. Goodluck my friend!
Answer:
Step-by-step explanation:
(6-2i)(2-3i)=
we will use foil to multiply
-12-18i-4i+6(i^2)=
now remeber that (i^2)=-1
=12-22i-6=<u>6-22i</u>
Answer:
9x+4y-17z

first open brackets with d signs
dat is= 4x+2y-6z+5y-2z+7x-9z-2x-3y
collect like terms and = 4x+7x-2x+2y+5y-3y-6z-2z-9z= 9x+4y-17z
