Answer:
Step-by-step explanation:
The first thing that you can do is to factor out an x^2 from the expression.
x^2(2x^2+4x-30)
The next step is to factor out a 2.
2x^2(x^2+2x-15)
Finally, you can factor the quadratic inside.
2x^2(x-3)(x+5)
And now you're finished! Hope this helps!
Answer:
200.96
or
201 (if you round it up)
Step-by-step explanation:
1) Well, if we know that the diameter (D) is 16 cm, then we know that the radius (r) is 8 cm (D = 2 * r).
2) Next, we square (^2) the radius, and we get 64 (r^2 = r * r = 8*8 = 64)
3) Finally, we multiply π by 64, and we get 200.96 cm^2 (3.14 * 64) which is very close to 201 cm^2.
Answer:
0.70512820512 round to the nearest hunderth
Step-by-step explanation:
The answer to this question is D
Prob (first defective) = 4 / 20 = 1/5
Prob(2nd defective) = 3/19
Prob (3rd defective) = 2/18 = 1/9
Pron 4th defective) = 1/ 17
Prob ( all 4 defective) = 1/5 * 3/19 * 1/9 * 1/17 = 1 / 4845 answer
