Answer:
54j + 72 + 9j and 63j + 72
Step-by-step explanation:
I just simplified it
So 9(6j + 8 + 1j) can be distributed to (9)(6j) + (9)(8) + (9)(1j) which equals 54j + 72 + 9j because 9*6j = 54 , 9*8 = 72 , and 9*1j = 9j
54j + 72 + 9j can also equal 63j + 72 because 54j + 9j = 63j
I hope this helped and I hope this is close to what you wanted heh :)
Answer:
s^4/r^2
Step-by-step explanation:
r^-2/ s^-4
When the exponent is negative, it moves from the numerator to the denominator or from the denominator to the numerator
r^-2 becomes 1 /r^2
1 / s^-4 becomes s^4
r^-2/ s^-4 = s^4/r^2
Looking at this we can group like terms. What are like terms? They are terms that have the same variable that we can add or subtract. In this case the like terms are 6m and m because they both have the same variable and we could add them together to get 7m.
Answer:
The annual rate of interest is 2 %
Step-by-step explanation:
Given as :
The investment amount = $ 3,500
The Interest earn on investment = $ 210
The time period = 3 years
Let The annual interest rate = R
From simple interest method :
Simple Interest =
Or, 210 × 100 = 3500 × R × 3
Or, R =
Or, R =
