Answer:
I believe it would be the first choice. Because you multiply the length and width both by 2. and then just add them together. which is what the first choice represents
You divide 13 and 20 which gives you <span>0.65<span><span><span><span><span>

69 - 3a = 0
69 - 3a (-69) = 0 (-69)

Answer:
38.46%
Step-by-step explanation:
There are no names or marking that can make the calculator look different, so the order is not important. Then we should use a combination to solve this problem.
There are 40 calculators in one shipment, 37 of them good items and 3 of them are defect items. We need to choose 19 good calculators and 1 defect calculator. The number of ways to do that will be:
* = 37!= 53017895700
The number of possible ways to choose 20 calculators out of 40 calculators will be:
= =137846528820
The chance will be: 53017895700/ 137846528820 = 0.3846= 38.46%
