Answer:
The answer can be 4 and nine or 6 and 6.
Step-by-step explanation:
I just looked at a multiplication chart and saw what numbers multiply to 36 and 6 and 6 and 4 and 9 were also on the chart.
Starting with x=1, subtract 1 from each side,
(x-1)=0
Our polynomial will have multiplicity of 2 for this particular zero,
(x-1)(x-1)
and do similar with the x=-4, add 4 to each side,
(x+4)=0
So our final result is: (x-1)(x-1)(x+4)
Expand out the brackets if you need this in standard form.
Answer:
D
Step-by-step explanation:
(given) -3(4x - 8) = -36
(distribute) -12x + 24 = -36
(subtract 24 from both sides) -12x = -60
(divide both sides by -12) x = 5
Answer:
522
Step-by-step explanation:
The assumption is that the proportion of tagged fish caught is the same as the proportion of all fish that were caught and tagged:
(all fish)/(number tagged) = (sample size)/(number in sample tagged)
all fish = (number tagged) · (sample size)/(number in sample tagged)
all fish = 174 · 39/13
all fish = 522
If all the assumptions are reasonable, the number of fish in the lake is estimated at 522.
