Answer:
x=-7
Step-by-step explanation:
Subtract 5 from both sides.
−x=12−5
Subtract 5 from 12 to get 7.
−x=7
Multiply both sides by −1.
x=−7
Answer:
Step-by-step explanation:
<u>Given function:</u>
<u>It can be rewritten as:</u>
- v(d) = 2^d, where d- number of divisions
<u>If number of divisions is 8, then:</u>
- v(8) = 2^8 = 256 virus cells
Correct choice is B
Shouldn't this be in the language section? But okay. I would say the simple subject would be "plane"
Answer:
The two roots of the quadratic equation are

Step-by-step explanation:
Original quadratic equation is 
Divide both sides by 9:

Add
to both sides to get rid of the constant on the LHS
==> 
Add
to both sides

This simplifies to

Noting that (a + b)² = a² + 2ab + b²
If we set a = x and b =
we can see that
= 
So

Taking square roots on both sides

So the two roots or solutions of the equation are
and 

So the two roots are

and
