For problem 2, it demonstrates an increase of 45%. This is simple, first find 45% of 140 by multiplying 140 by .45 which should get you to 63. Then because it is INCREASING by 45%, add 63 to 140 which equals 203, so your final answer is 203.

For question 4, it demonstrates a DECREASE of 80%, so we would use the same process but SUBTRACT instead. Find 80% of 75 by multiplying 75 by .8, which is equal to 60. Now, because it is a DECREASE of 80%

140 * .45 = 63
Add 140 and 63
2. 203 because you are adding 45% of 140 to increase it by 45%
Same with the other except subtraction

How do i factor s^2+9s=-20
Talja [164]
To factor you have to do this: 

s^2 + 9s = -20
      + 20    +20

s^2 + 9s + 20 = 0

now you need to numbers that multiplied give you 20 
and then those same 2 numbers have to add to 9

5 x 4 = 20
5+ 4 = 9

(x + 4) (x+ 5)

that means that x= -4, and -5

P(TTTTT)=P(T)*P(T)*(PT)*P(T)*P(T)

P(TTTTT)=(P(T))^5

P(T)=1/2 so

P(TTTTT)=(1/2)^5

P(TTTTT)=1/32

P(TTTTT)=3.125%
