the base must be raised
for example
55 = n ( the base is 10 ), then
55 = 
Answer:
Step-by-step explanation:
2 * L + 2 * W = 68
2*L = 2* 9x = 9x + 9x
2*W = 2*8x = 8x + 8x
Since the perimeter is 68
9x + 9x + 8x + 8x = 68
Hello kiddio lets figure this out!
The formula for simple interest is I = P*R*T where I = interest, P = Principal (original amount), R is the rate as a decimal, and T is time in years. So I = 1500*(.05)*6 = 1500*(0.30) = $450. The total amount you have after 6 years is the amount you started with ($1500) plus the interest ($450) which is $1950. The formula for yearly compounding is A = P(1 + r)t where A = Accumulated or final amount P = Principal ($1500) r = interest rate as a decimal (0.05)t = time (6 years) A = 1500*(1 + 0.05)6 = 1500*(1.05)6 = $2010.14
Have a nice day
Distribute on the left side
7.4a+22.2=3.2a+43.2
Subtract 3.2a from both sides
4.2a+22.2=43.2
Subtract 22.2 from both sides
4.2a=21
Divide both sides by 4.2
a=5
