-50= 2x^2-12x-32
2x^2-12x-32+50
2x^2-12x+18
2(x^2-6x+9)
2(X-3)(X-3)
X-3=0
X=3
Answer:
4. Multiply both sides by -2 => x - 7 = -36, Add 7 to both sides -> x = -29
5. Add 12 to both sides => 28 = 1/4x, then multiply both sides by 4 => 112
x = 112
7. Multiply both sides by 3 => 5x - 2 = 63, add 2 to both sides => 5x = 65,
Divide both sides by 5 -> x = 13
10. Multiply both sides by 6 => 132 = 3x - 6, Add 6 to both sides => 138 = 3x,
Divide both sides by 3 => x = 46
Step-by-step explanation:
Answer: Rectangle around the cylinder, Lateral surface of the cone, Half a sphere
To find this surface area, you have 3 different parts. First, you need the rectangular portion of the cylinder, because the circles will be on the inside of the composite shape. Then, you will need the lateral side of the cone, that's everything but the circular base. Again, the circle will be on the interior. Finally, you should find the surface area of half of the sphere.
Answer:
The correct answer would be 37.5, but since you cant have half a table, its rounds up to A., 37. Hope you found this helpful, and if so, please mark as Brainliest! (:
Answer:
942
Step-by-step explanation:
If 5 is the radius and 12 is the height, and the formula of a cylinder is V=πr^2h, we can substitute.
V=π(5)^2(12)
5^2 is 25, and 25 times 12 is 300.
300π, and that would be approximately 942.
