Factor completely x^8 − 16. (x4 − 4)(x4 + 4)
(x2 − 2)(x2 + 2)(x4 + 4)
(x2 − 2)(x2 + 2)(x4 − 4)
(x2 − 2)(x2 − 2)(x4 − 4)

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

​    

=240

=48

step-by-step explanation:

2/4 is the answer

step-by-step explanation:

x= total pieces

both ate 9 pieces

mindy ate 3 so troy ate 6

6= (1/4)x

x =24

answer: (x+2) (x+3) are the binomials for your question : )
