Answer:

<u><em>V = 1,500 </em></u>cm^{3}

Step-by-step explanation:

First off, we have to identify the formula in which we are using:

V = \frac{1}{2} a*c*h

<em>Where:</em>

a = 12

c = 10

h = 25

<em>Next, plug in the numbers:</em>

V=\frac{1}{2} (12)(10)(25)

<em>Now, calculate:</em>

V = 1500 cubic centimeters

The difference of 2 numbers is 3 and their sum is 25. What are the numbers? 10 and 15 14 and 11 11 and 13 13 and 12
vagabundo [1.1K]

Let the two numbers be x and y

As given, the difference of two numbers is 3, so

x-y=3  or x=3+y ....(1)

And their sum is 25, so

x+y=25   .....(2)

Putting x=3+y in equation (2)

3+y+y=25

2y=22

y=11

As, x+y=25

x+11=25

x=14

So the two numbers are = 14 and 11

Answer:

Hi there!

The correct answer is: (x+8)² = 73

Step-by-step explanation:

First you want to modify the equation: x² + 16x - 6 = 3 into x² + 16x = 9 by adding 6 on both sides.

Then you analyze the new equation, if you can see, 16x is positive which means two positive numbers have to be added up to equal a positive. Which eliminates the choices that have (x-8)²

And now you are left with two choices:

(x+8)² =73 and (x+8)² = -55

Now remember, when you factor out (x+8)² it equals to x² + 16x + 64

next let's bring it back to the very first equation: x² + 16x = 9

now which choice matches the result x² + 16x = 9. The answer will be (x+8)² = 73 because when you subtract 64 on both sides you get 9.
