3m+21=6m
=>21=6m-3m
=>21=3m
=>7=m
Therefore option A is the answer
Answer:
1/4 hr longer
Step-by-step explanation:
<span>Let us denote the amount of investment in the Fund B with x. We know that Fund B returned 8% and that in Fund A Nicole invested </span>$3000 less than the amount she invested in Fund B, so we can write: x-3000<span>Fund A returned 6%.
Interest = 2060
The percent has been converted by multiplying the equation by 100
8x+6(x-3000)= 2060*100
8x+6x-18000=206000
</span><span>14x=206000+18000
14x=224000
x=16000
Nicole invested in Fund B $16000 and in Fund A </span><span> $16000-3000=13000.</span><span>
</span>
We are asked to factor out the expression:
4 x^3 - 10 x
So we extract a factor of "2" from the numerical factors "4" and "10", and also a factor of "x" from each term,leading to:
2 x ( 2 x^2 - 5)
Therefore, please select the first answer option they give you in the list.
