Answer:
The bullet point between the numbers means times in this case, in some other cases it would mean "and" also known as plus. Therefore, the correct answer is the second one.
Step-by-step explanation:
In each half unit cube there is 6 cubes. ⇒
6 + 6 + 6 = 18 ⇒
But, this is not one of the options.⇒
So, we have to make the equation a bit different to solve it. ⇒
2 x 3 x 2, is the first option. ⇒
This is incorrect, as it equals 12. ⇒
The sum we are looking for is 18. ⇒
The second answer is 2 x 3 x 3. ⇒
This equals 18, we have found the correct answer. ⇒
So, there are a total of 3 half-unit cubes. ⇒
There are a total of 18 cubes. ⇒
I hope this helps!
Yes you have the correct answers for each of the four problems. Nice work.
For anyone curious,
rd = removable discontinuity
id = infinite discontinuity
c = continuous
I think it’s because they are opposite so Yh sos if it’s wrong
Answer: f(a-2) = 2a² - 14a + 28
Step-by-step explanation:
f(x) = 2x² - 6x + 8
you can take a-2 and substitute it for each x, which would look like this:
f(a-2) = 2(a-2)² - 6(a-2) + 8
then distribute those in ( )
f(a-2) = 2a² - 8a + 8 - 6a + 12 + 8
combine like terms
f(a-2) = 2a² - 14a + 28
