I got 2,592 ft^3

explanation (little figure on top): base is 9, height is 6, and length is 12.
9 x 6 x 12 = 648 cubic feet.

explanation (larger figure): base is 27, height is 6, and length is 12.
12 x 6 x 27 = 1,944 cubic feet.

now add the two together to get the whole volume.. 1,944 + 648 = 2,592 ft^3

hope this helps!

Let u = <-9, 4>, v = <8, -5>. Find u - v. <br> URGENT

Pie

To subtract vectors, you simply have to subtract correspondent coordinates.

So, if you have

$u = \langle u_1,\ u_2,\ldots u_n\rangle ,\quad v = \langle v_1,\ v_2,\ldots v_n\rangle$

the subtraction is simply

$u-v = \langle u_1-v_1,\ u_2-v_2,\ldots u_n-v_n\rangle$

So, in your case, we have

$\langle-9,4\rangle-\langle 8,-5\rangle=\langle -9-8, 4+5\rangle=\langle -17,9\rangle$

2. Solve. x2 - 72 = 0

Effectus [21]

Answer:

x = ± 6 $\sqrt{2}$

Step-by-step explanation:

Given

x² - 72 = 0 ( add 72 to both sides )

x² = 72 ( take the square root of both sides )

x = ± $\sqrt{72}$ = ± $\sqrt{36(2)}$ = ± 6 $\sqrt{2}$

The surface area of a cube is 216 sq.cm. What is it’s volume

PtichkaEL [24]

First we need to find it’s length/width which we can do by dividing 216 by the amount of faces it has and then divide that result by 2

216/6=36
36/2=18

And volume is pretty much just 3 times that answer

3(18)=54

The volume is 54 cm^3
