Answer:

300

Step-by-step explanation:

Because of PEMDAS (Order of Operations), you would do the exponent first.

So, 3(x)^2 and 3(100)

Then you get 300

Hope this helps!

What is the solution of the following question?<br> x^2+10x+25=12
zalisa [80]
Make equal to 0
minus 12from both sides
x^2+10x+13=0
we can't factor so use quadratic formula

x= \frac{-b+/- \sqrt{b^{2}-4ac} }{2a}
x= \frac{-10+/- \sqrt{10^{2}-4(1)(13)} }{2(1)}
x= \frac{-10+/- \sqrt{100-52} }{2}
x= \frac{-10+/- \sqrt{48} }{2}
x= \frac{-10+/- 4\sqrt{3} }{2}
x= -5+/- 2\sqrt{3}


x= -5+ 2\sqrt{3} or -5- 2\sqrt{3}

aprox
x=-1.5359 or -8.4641

12.<br>The container shown has a capacity of 60 milliliters.<br>What fraction of it is empty?<br>​
White raven [17]

This is an incomplete question, the image is shown below.

Answer : The fraction empty container is, \frac{7}{12}

Step-by-step explanation :

As we are given that:

The capacity of container = 60 mL

In the given figure, the container is filled with 25 mL.

That means,

60 - 25 = 35 mL container is empty.

Now we have to calculate the fraction of it is empty.

The fraction of it is empty = \frac{\text{Capacity of empty container}}{\text{Total capacity of container}}

The fraction of it is empty = \frac{35mL}{60mL}

The fraction of it is empty = \frac{7}{12}

Therefore, the fraction empty container is, \frac{7}{12}
