Answer:

3x+3=12

Step-by-step explanation:

You do 3 times x which equals 3x and then you do 3 times 1 which is 3. so the problem is 3x+3=12, and then do 3-3, not 3x - 3. It's just 3-3, and then after that 12-3=9 9 divided by 3 is 3. x is the number that helps it go into that number

x=3.

Perform the indicated operation. (y4 - 1) ÷ (y + 1)

olya-2409 [2.1K]

Factorize the numerator as a difference of squares:

$y^4-1=(y^2-1)(y^2+1)=(y-1)(y+1)(y^2+1)$

Then if $y\neq-1$ , the $y+1$ factors will cancel:

$\dfrac{y^4-1}{y+1}=(y-1)(y^2+1)=y^3-y^2+y-1$

so the answer is B.
