you would factor using the perfect square method to get
(3m+5n)^2
Answer:
6.23 gallons per square foot
Step-by-step explanation:
623/1000 = 6.23
Write an equation system based on the problem. For an instance, x represents the number of $3 tickets sold and y represents the number of $5 tickets sold.
x + y = 40
3x + 5y = 136
Solve the equation system using elimination method. Use elimination of y in order to find the value of x
x + y = 40 (multiplied by 5)
3x + 5y = 136 (multiplied by 1)
-----------------------------------------
5x + 5y = 200
3x + 5y = 136
------------------ -
2x = 64
x = 64/2
x = 32
The value of x is 32. She sold 32 tickets worth $3
Yes it is. log(1) and ln(1) both equal zero. But you cannot take the logarithm of 0.
