Answer:

576

Step-by-step explanation:

The volume of a square pyramid is $\frac{a^2h}{3}$ , where a is the base length and h is the height. We know that a is 8 so a squared is 64. 64x27=1728, and 1728/3 is 576. So the volume of the pyramid is 576 units cubed.

Hope this helps!

dimulka [17.4K]

Answer:

$\left[\begin{array}{cccc}-12&-13&13&|15\\7&-10&-3&|11\\7&14&5&\:\:\:|-5\end{array}\right]$

Step-by-step explanation:

The system of equations is;

-12x-13y +13z =15

7x-10y-3z = 11

7x+14y +5z = -5

The coefficient matrix is $\left[\begin{array}{ccc}-12&-13&13\\7&-10&-3\\7&14&5\end{array}\right]$

The constant matrix is $\left[\begin{array}{c}15\\11\\-5\end{array}\right]$

The augmented matrix is $\left[\begin{array}{cccc}-12&-13&13&|15\\7&-10&-3&|11\\7&14&5&\:\:\:|-5\end{array}\right]$

I need help on my math homework

Answer: the first one is True and the second one is false

Step-by-step explanation:

3 + 5x = 23

so replace x with 4 you get 3 + 5 * 4 = 3 + 20 = 23

this is equal to 23 so it is true

2x - 6 = 9

do the same you get

2 * 8 - 6 = 9

16 - 6 = 10

the answer is 10 not nine therefore it is false
