Answer:
what is it equal to
Step-by-step explanation:
If you would like to evaluate A^2 for A = - 3, you can do this using the following step:
A^2 = (-3)^2= +9 = 9
If you would like to evaluate 2 * A for A = -3, you can do this like this:
2 * A = 2 * (-3) = -6
Answer:
128 cm3
Step-by-step explanation:
we know that
The volume of the square base pyramid is equal to
![V=\frac{1}{3}b^2h](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B1%7D%7B3%7Db%5E2h)
where
b is the length side of the square base
h is the height of the pyramid
we have
![h=6\ cm](https://tex.z-dn.net/?f=h%3D6%5C%20cm)
![b=h+2](https://tex.z-dn.net/?f=b%3Dh%2B2)
substitute the value of h
![b=6+2=8\ cm](https://tex.z-dn.net/?f=b%3D6%2B2%3D8%5C%20cm)
Find the volume
![V=\frac{1}{3}(8)^2(6)=128\ cm^3](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B1%7D%7B3%7D%288%29%5E2%286%29%3D128%5C%20cm%5E3)
Answer:
x = ![\frac{m-a}{12}](https://tex.z-dn.net/?f=%5Cfrac%7Bm-a%7D%7B12%7D)
Step-by-step explanation:
Isolate the term in x by subtracting a from both sides
12x = m - a ← divide both sides by 12
x = ![\frac{m-a}{12}](https://tex.z-dn.net/?f=%5Cfrac%7Bm-a%7D%7B12%7D)
The solution would be like this for this specific problem:
12! = 12 * 11 * 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1
= 479,001,600

there are 479,001,600 <span>different group of students that can show up
for a seminar with an enrollment of 12.</span></span>
