Answer:
x=3
Step-by-step explanation:
The greatest common factor in this expression is 3x^4. Let's take it out:
3x^4(u^4 - 1)
u^4 - 1 is a difference of two squares and can be factored further:
3x^4(u^2 + 1)(u^2 - 1)
u^2 - 1 is also a difference of two squares:
3x^4(u^2 + 1)(u + 1)(u - 1)
Answer:
It's D: 3x - 12 ≤ 8x + 13
Step-by-step explanation:
<u>The first step in this inequality is to take out the parentheses so you multiply 3 by x and -4.</u>
Answer:
Interest= $423.59
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $6,000
Number of periods (n)= 3 years
Interest rate (i)= 2.3% = 0.023
<u>To calculate the Future Value, we need to use the following formula:</u>
FV= PV*(1+i)^n
FV= 6,000*(1.023^3)
FV= $6,423.59
<u>Now, the interest earned:</u>
<u />
Interest= 6,423.59 - 6,000
Interest= $423.59
