2D-a^2=2

2(a√2) -a^2=2

a^2-2√2*a+2=0

2a= 2√2 + √(8-4*2) = 2√2 
hence, perimeter = 4a = 2*2a=2*2√2 = 4√2

3. A train set costs $120.00. Find the discount if it is on sale for<br> 30% off.
Leno4ka [110]

Answer:

36

Step-by-step explanation:

To find the discount, you will need to find 30% of $120, so you will need to do:

120*0.3=36

Also, if you were asking for the COST if it was 30% off, it would be 84 as 120-36=84.

(I hope this helps!)
