Answer: (x-1)(3x+8)
Step-by-step explanation:
Slide and divide method
See what multiplies to get -24 (because of 3 and -8) and what adds to get 5
Put those into factoring form (x-3)(x+8) without a number in front of the x’s
Divide the numbers by what isn’t in front of the x’s (-3/3 and 8/3)
Simplify them and if it doesn’t divide perfectly, put the denominator in front of the x
Solution
**I can’t explain it well but watch a video on the method AND ONLY DO IT IF IT WORKS WELL FOR YOU**
Answer:
V = (1/3)πr²h
Step-by-step explanation:
The volume of a cone is 1/3 the volume of a cylinder with the same radius and height.
Cylinder Volume = πr²h
Cone Volume = (1/3)πr²h
where r is the radius (of the base), and h is the height perpendicular to the circular base.
_____
<em>Comment on area and volume in general</em>
You will note the presence of the factor πr² in these formulas. This is the area of the circular base of the object. That is, the volume is the product of the area of the base and the height. In general terms, ...
V = Bh . . . . . for an object with congruent parallel "bases"
V = (1/3)Bh . . . . . for a pointed object with base area B.
This is the case for any cylinder or prism, even if the parallel bases are not aligned with each other. (That is, it works for oblique prisms, too.)
Note that the cone, a pointed version of a cylinder, has 1/3 the volume. This is true also of any pointed objects in which the horizontal dimensions are proportional to the vertical dimensions*. (That is, this formula (1/3Bh), works for any right- or oblique pyramid-like object.)
__
* in this discussion, we have assumed the base is in a horizontal plane, and the height is measured vertically from that plane. Of course, any orientation is possible.
Answer is 120
1/2 of 120 is 60
1/3 of 60 is 20
therefore, leaving 40 left
Let one of those numbers be x.
Now,
according to question,
The other number must be,
3x-6
Now,
as said in the question,
x+3x-6 =62
4x -6 =62
4x = 68
x = 17.
Now,
we got one of those numbers which was x = 17,
and the other number should be 3(17)-6 = 51-6 = 45.
