Answer:
a=2
Step-by-step explanation:
5+14a=9a-5 subtract 9a from both sides
5+5a=-5 subtract 5 from both sides
5a=-10 divide by 5 on both sides
a=-2
hope you do well :)
X^2+9x+9x+81
x^2+18x+81
for factoring it
<span>3b + 2(b − 1) = 8
3b + 2b - 2 = 8
5b = 10
b = 2
answer b = 2</span>
Answer: 448 dollars
=============================================
Work Shown:
P = 400 is the balance
r = 0.12 is the decimal form of the interest rate
t = 1 is the number of years
Use those values to get the simple interest to be
i = P*r*t
i = 400*0.12*1
i = 48
The amount of interest charged is $48
Add this onto the balance of 400 dollars and the total amount Aaron owes is P+i = 400+48 = 448 dollars.
