Answer:
4ab(3a² + 2ab − 5b²)
Step-by-step explanation:
simply factorize
Answer:
7.5
Step-by-step explanation:
divide both in half and add them
Answer:
Step-by-step explanation:
Since we have an x under that radical, we have to get it out from under there. To do that, do the opposite of the square root, which is to square. But because this is an equation, you have to do the same thing to both sides. Doing this gives you

Get everything on one side and set the quadratic equal to 0 and solve for x:

Factor this into 2 factors of (x - 3)(x - 3) = 0. As you can see they are both the same, so x - 3 = 0 and x = 3. That's your answer. x = 3.
180*60%=180*60/100=10800/100=108
180+108=288
So the total population os school is 288 students!

Answer:
Option B.
Step-by-step explanation:
If a quadratic equation is defined as
, the by quadratic formula

Consider the given equation is

We need to find the value of x.
Add 96 on both sides.


Here, a=1, b=14 and c=113. Using quadratic formula we get





The value of x are x=-7 + 8i and x=-7 - 8i.
Therefore, the correct option is B.
