(x + 2)(5x^2 + x - 4) =
x(5x^2 + x - 4) + 2(5x^2 + x - 4) =
5x^3 + x^2 - 4x + 10x^2 + 2x - 8 =
5x^3 + 11x^2 - 2x - 8 <===
The second option ! 2.54 - 2.3 = 0.24
<span>K = 3D. K - 4 = 5(D - 4). K - 4 = 5D - 20. K = 5D - 16. 3D = 5D - 16. 16 = 2D. D = 8. K = 3 x 8. K = 24.</span>
Answer:
DAM BROOOOO UR SCREEN.
Step-by-step explanation:
Answer:
The person invested $3500 at 7% and $2500 at 5%
Step-by-step explanation:
We can say that
because the investment is equal both in one as in another, where x is the income from the investment.
Solving the equation we have:
![0,12x=6000\\x=50000](https://tex.z-dn.net/?f=0%2C12x%3D6000%5C%5Cx%3D50000)
Then to get the incomes:
At 7%: ![I=0.07*50000\\I=$3500](https://tex.z-dn.net/?f=I%3D0.07%2A50000%5C%5CI%3D%243500)
And at 5%: ![I=0.05*50000\\I=$2500](https://tex.z-dn.net/?f=I%3D0.05%2A50000%5C%5CI%3D%242500)
Finally we can demonstrate the answer because the income at 7% + income at 5% are 3500+2500=$6000
