Answer:
Factor 3x^2-17x-20, and you get (x + 1)(3 x - 20)
x = 17/6 + sqrt(1729)/6, x = 17/6 - sqrt(1729)/6
Step-by-step explanation:
Factor 3x^2-17x-20, and you get (x + 1)(3 x - 20)
When 3x^2-17x-20 is equal 100
3x^2-17x-20=100
Subtract both sides by 100
3x^2-17x-120=0
Use the quadratic formula
x = 17/6 + sqrt(1729)/6, x = 17/6 - sqrt(1729)/6
<span>To find the circumference, the area first needs to be found to discover the radius. Area equals (r^2) multiplied by pi, or approximately 3.14. In this case, 12.5/3.14 gives a radius^2 of 3.98 feet. The square root of 3.98 is 1.99 feet. Using the radius, the diameter and circumference can now be found. The diameter is (2r), which would also be 3.98 feet in this case. 3.98 * 3.14 gives a circumference of 12.4972 feet.</span>
Answer:
The surface area of a cube = 6a2 where a is the length of the side of each edge of the cube. Put another way, since all sides of a cube are equal, a is just the lenght of one side of a cube. We have 96 = 6a2 → a2 = 16, so that's the area of one face of the cube.
