Answer:

(x+1-i)(x+1+i)

Step-by-step explanation:

(x+1-i)(x+1+i)\\\\=(x+1)^2 -i^2~~~~~~~~~~~~~;[a^2 -b^2 = (a+b)(a-b)]\\\\=x^2 +2x +1 -(-1)\\\\=x^2 +2x +1+1\\\\=x^2 +2x +2

Answer:

no

Step-by-step explanation:

The correct explanation is A

\frac{x^{m} }{a^{n} } = a^{(m-n)}

Thus

\frac{9.2}{4} × \frac{10^{8} }{10^{-3} }

= 2.3 × 10^{(8-(-3))}

= 2.3 × 10^{11}

1) What is 15\50 in lowest terms
zaharov [31]
15/50 simplified would be 3/10 (divided by 5 on each side)
5/9 x 3/10 would be 15/90 or 1/6
1/4 divided by 3/5 would be 5/12, because when you divide fractions you flip the second fraction Ex: 1/4 divided by 3/5 would be 1/4 x 5/3
The prime factorization of 120 would be 2 x 2 x 2 x 3 x 5 or 2^3 x 3 x 5

Please explain how to get the answer
meriva
Q must be positive in F.

F. r squared will be positive, because any number times itself is positive, and to get a positive number for the answer, the two numbers you multiply need to be the same sign. If r squared is positive, q must be too. 

G. q does not have to be positive. If r is a negative number, then q can be negative. Say q=-2 and r=-3. -2-(-3) changes to -2+3, which equals 1.

H. Again, q can be negative if r is negative (two negative numbers multiplied together equals a positive answer.

J. q can be negative because even a negative number turns positive when squared.

Hope this helped you. :)
