We have the following expression:

(2a^2 - 8)(4a^4 + 16a^2 + 64)

So let's solve this problem step by step.

1st. Applying distributive property:

(2a^2)(4a^4+16a^2+64)-8(4a^4+16a^2+64)

2st. Applying distributive property again:

8a^6+32a^4+128a^2-32a^4-128a^2-512

3st. Grouping terms with the same base:

8a^6+(32a^4-32a^4)+(128a^2-128a^2)-512

4st. Solving, the result is:

8a^6-512

HACTEHA [7]

The price of the stock of PEV Corporation varies as shown. we have to determine the net charge. Net change is just how much it changed overall, so we will look for all the ups minus all the downs.  

Here, "went up" goes with a + sign, and "went down" goes with a - sign.

So, Net charge = \frac{1}{4} - \frac{1}{3}-\frac{3}{4} + \frac{7}{10}

= \frac{1}{4}-\frac{3}{4}- \frac{1}{3} + \frac{7}{10}

= -\frac{2}{4}- \frac{1}{3} + \frac{7}{10}

= -\frac{1}{2}- \frac{1}{3} + \frac{7}{10}

LCM of 2,3 and 10 is 30

= \frac{-15-10+21}{30}

= \frac{-4}{30}

= \frac{-2}{15}

So, the net charge is \frac{-2}{15}
