Answer:
(x-2), (x+2), (3x-5)
Step-by-step explanation:
Factors of 3: ±1, ±3
Factors of 20: ±1, ±2, ±4, ±5, ±10, ±20
Possible factors of the polynomial: ±1, ±2, ±3, ±4, ±5, ±10, ±20, .... (there's a lot more but you probably do not need to list them all)
Pick a number to divide the polynomial by (I picked 2)
(3x³-5x²-12x+20)÷(x-2) = 3x²+x-10
So (x-2) is a factor of f(x) = 3x³-5x²-12x+20
Factor 3x²+x-10 = (3x-5)(x-2) these are the other factors of f(x) = 3x³-5x²-12x+20
Answer:
2827.43in²
Step-by-step explanation:
formula for area of a circle is r²π with r being the radius (30 in this case)
we can plug in 30 for r to solve for the area
30²π
900π
2827.43
that is the answer

Answer:
s≤4 cm.
Step-by-step explanation:
Let s be side of cube.
As we know that the volume of cube=side×side×side
Here, it is given that the volume of cube = 64 cubic centimeters.
or we can write
side×side×side=64 cubic centimeters
Taking cube root both sides
side= 4 cm
In order to build a cube with a minimum of 64 cubic centimeters,
we can take the value of s≤4 cm.
Hence, the reasonable range for s, the side length is s≤4 cm.
