Answer:
Combine like terms; 3x + 5x= 8x
Since you don't have any like terms for +8, it's going to remain the same and not change.
Answer : 3x + 5x + 8 = 8x + 8
Again with combining like terms, 4x + 4x = 8x
Answer: 4x + 4x = 8x
The third expression is going to be very similar to the last problem. 4x + 4x + 4x + 4x. We're going to add the terms together. 4+4+4+4 is equal to 16. Bring the x down and you get...
Answer: 16x
Lastly, we have -7x + 4 + 3x. Do the exact same thing we did to the other problems, combining like terms, shocking, I know. -7x + 3x= -4 and since there's no other like terms for +4, it stays the same. Therefore
Answer: -7x + 4 + 3x = -4 + 4

The nearest hundred thousand is 3,700,000
And the nearest million is 4,000,00
Answer:
B. $5039.58
Step-by-step explanation:
compound interest formula: amount = p(1 + \frac{r}{n})^{nt}
p= principal ($2,300)
r= interest rate as a decimal (4% = 0.04)
n= number of times the principal is compounded per year (annually = onceper year so 1 time per year)
t= time in years (20 years)
new equation: amount = 2300(1+\frac{0.04}{1} )^{1*20}
That equation equals $2,739.58 which you add to the principal.
$2,739.58 + $2,300 = $5039.58
hope this helps :)
