Answer:
Step-by-step explanation:
So the chance of getting yellow is 0.25
Getting it once is 0.25
Getting it twice is 0.25 • 0.25
Not getting it is 0.75
So we have 0.25 • 0.25 • 0.75 • 0.75 • 0.75 =
1/4a + 1/3a +8 =22
1st step add like terms:
1/4a +1/3a = 3/12a +4/12a = 7/12a
7/12a +8 =22
2nd step subtract 8 from each side:
7/12a = 14
3rd step divide both sides by 7/12 to get a:
a = 14 / 7/12
a = 24
The answer is the third one
If it has no stretch factor, then there will be no coefficient. Meaning this is a lot easier. So, we equation is
(x+6)^2 + 5

5x - 20 = 8x - 65
-20 = 3x - 65
3x = 45
x = 15
