-x^2
Is that x times -x?
positive times a negative is negative
and you add the exponents when multiplying like base
Answer:
(1 -2y)(1 +2y)
Step-by-step explanation:
The difference of squares is factored as ...
... a² - b² = (a -b)(a +b) . . . . . . . . a form you should keep handy
Here, you have a=1, b=2y, so your factored form is ...
... 1 -4y² = (1 -2y)(1 +2y)
Answer: (A) 30%
Step-by-step explanation:
Given : The probability that a bird will lay an egg =0.75
The probability that the egg will hatch =0.50
Now, the probability that the egg will lay an egg and hatch = 
Also,The probability that the chick will be eaten by a snake before it fledges =0.20
Then, the probability that the chick will not be eaten by a snake before it fledges : 1-0.20=0.80
Now, the probability that a parent will have progeny that survive to adulthood will be :-

Hence, the probability that a parent will have progeny that survive to adulthood = 30%
8 · 7 = 56, therefore LCM(8, 56) = 56.
If you’re asking for just the number of pounds then the answer is
200-33= 167 pounds
If you’re asking for a percentage of decrease it will be
200 - 33 = 177
_______ ____ = 0.885 x 100 will equal to 88.5% decrease.
