Hello there!

The answer is 13 trust me. the answer should be 29 for no reason. but answer 13 and you'll get it right.

I don't know how to take a screen shot and post. but the easy way is to count . so 50 years old = 15. 60 years old = 8. 70 years old = 4. 80 years old = 2. add them.

A student factors a^6 - 64 to (a^2 - 4)(a^4 + 4a^2 + 16). Which statement about (a^2 − 4)(a^4 + 4a^2 + 16) is correct?
Lorico [155]
So that equation was definitely correct...

When you expand the equation in the bracket you'll find out that you'll get a^6 + 4a^4 + !6a^2 - 4a^4 - 16a^2 -64. then your final result will be a^6 - 64
