Step-by-step explanation:
a · b = (4)(3) + (5)(6)
a · b = 12 + 30
a · b = 42
Answer:
2 out of 5
Step-by-step explanation:
I believe that 96/240 needs to be simplified until it cant anymore, an that is the probability because they both fit three, I will divide by three.
96/3=32
240/3= 80
<u>32/80</u>
2
16/40 then because they both fit four, Ill do four.
4/10then 2 again
2/5 so, it is 2 out of five
please correct me if I am wrong, I was never good at probabilities, but I am better now.
You did the problem perfect good job
Answer:
Step-by-step explanation:
I = V / R
Current = (voltage) / (resistance)
Current = (500 V) / (250 ohms)
Current = (500/250) Amperes
Current = 2 Amperes
Answer: Mustafa is incorrect. He made a mistake in step 2.
Step-by-step explanation: Mustafa was certainly correct in step 1 that x(9x+3) + 3(x+3) is 9x^2 + 6x + 9. However when he was factoring, he made a mistake.
(3x + 3)^2 is NOT equal to 9x^2 + 6x + 9. Rather, (3x + 3)^2 is equal to 9x^2 + 18x + 9. If you want to double check this, use FOIL.
The correct factoring of 9x^2 + 6x + 9 is actually 3(3x^2 + 2x + 3). So, Mustafa made a mistake in step 2.
