A. 2(z2 + 1)(z2 – 1)
B. 2(z2 + 1)(z – 1)(z + 1)
C. Prime
D. 2(z2 + 1)2
Answer:
The correct answer is B,
Step-by-step explanation:
Since the higher value of z's power, is 4, an even number, and the second number is negative, we can think that this binomial is made of a difference of squares, so that is what we are going to factorize.
First, extract the common number (if any), the number 2, we have now>
This is convenient since "1" is a wonderful number that has this feature> No matters what n's value is,
so the first equation can be written as
The later termn, can also be factorized, using the same as befre.
Remember that
Answer:
y = 2 x - 9
Step-by-step explanation:
slope = difference of y / difference of x
m = (-5 - (-1)) / (2 - 4) = -4 / -2 = 2
pass point (4 , -1)
y = mx + b b: y intercept
b = y - mx = -1 - 2 x 4 = -9
equation: y = 2 x - 9
Answer:
Time taken would be = 12 minutes to print the payroll if both computers are used
Step-by-step explanation:
Computer A Takes = 20 minutes
Computer B Takes = 30 minutes
To Find:
Time to print if both were used = ?
Solution :
Now We will first calculate How much work is done by each computer in one minute
Computer A will do = 1/20 Work one minute
Computer B will do = 1/30 work in one minute
Now if both computers are used then
work done by both of them in one minute would be sum of both the computers f the work together
So
it would be
Work done =
Taking LCM and solving
Work done =
=
=
Now to do the whole task Time taken would be reciprocal of Work done in one minute
So
Time taken would be = 12 minutes
Answer: It would take 52 minutes
Step-by-step explanation:
20+32=52
