Answer:
D. 3(x - 1)(x+3)(x + 2).
Step-by-step explanation:
3(x - 1)(x + 3)(x + 2)
= 3(x - 1)(x^2 + 5x + 6)
= 3(x^3 + 5x^2 + 6x - x^2 - 5x - 6)
= 3(x^3 + 4x^2 + x - 6)
= 3x^3 + 12x^2 + 3x - 18.
If you’re trying to find the area of the step:
A=lwh
A=20•15•8
A=2,400 cubic inches
or 2,400 in ²
Answer:
0.08 or 8%
Step-by-step explanation:
to find probability, number of left handed/total
this would be (9+3)/(90+60), which simplifies to 12/150 = 0.08.
Answer:
5
Step-by-step explanation:
<span><span><span><span>−<span>x2</span></span>−<span>4x</span></span>+5</span>>0</span>
Let's find the critical points of the inequality.<span><span><span><span>
−<span>x2</span></span>−<span>4x</span></span>+5</span>=0</span><span><span><span>
(<span><span>−x</span>+1</span>)</span><span>(<span>x+5</span>)</span></span>=0</span>(Factor left side of equation)<span><span><span><span>
−x</span>+1</span>=<span><span><span>0<span> or </span></span>x</span>+5</span></span>=0</span>(Set factors equal to 0)<span><span>
x=<span><span>1<span> or </span></span>x</span></span>=<span>−5</span></span>
Check intervals in between critical points. (Test values in the intervals to see if they work.)<span>
x<<span>−5</span></span>(Doesn't work in original inequality)<span><span><span>
−5</span><x</span><1</span>(Works in original inequality)<span>
x>1</span>(Doesn't work in original inequality)
Answer: −5<x<1
