The area is 36 and the perimeter is 26
Answer:
So we first open multiply the parenthesis by 9. 9x+5 is what it is. Now we need to simply it even more with the 2 parenthesis
(9x+5)(x+1) = 9x^2+9x+5x+5 = 9x^2+14x+5
<h2><u>
Answer: 9x^2+14x+5</u></h2>
Answer:
The probability is:

Step-by-step explanation:
Keep in mind that the probability of getting a head is always the same for each

Therefore the probability of not having a head is:

So if we throw the coin 4 times the probability P of not getting any head is:


20/5 = 4 half lives
so
<span>300 * (1/2)^4
</span>= 300 * 0.0625
=18.75 grams
