It all depends on the math question but usually you solve for x, then check it. Plug x back in and see if it works. But it all depends on the math problem
Answer:
A
Step-by-step explanation:
x² - 3x - 54 = 0
x² - 9x + 6x - 54 = 0
x(x - 9) + 6(x - 9) = 0
(x - 9)(x + 6) = 0
x = -6,9
Answer: 12√2 cm
<u>Step-by-step explanation:</u>
Cube 1: V = 6³ = 216
Cube 2: V = 8³ = 512
Cube 3: <u>V = 10³ = 1000</u>
New Cube: V = 1728
1728 = s³
12 = s
So, each side of the new cube is 12 cm.
Use Pythagorean Theorem to find the length of the diagonal:
12² + 12² = diagonal²
144 + 144 = diagonal²
288 = diagonal²
√288 = diagonal
12√2 = diagonal
If you know the volume then:
(3 * Cone Volume) / (PI * radius^2) = height
(3,2) is the center and the radius is 2. You can see this by taking where the dot is in the graph (in this case (3,2)) that is your middle, while the radius is one half of the circle, basically how many points are between the circle and the dot. Hope this helps!
