Answer:
The correct options are;
B) and D)
Step-by-step explanation:
In the question, we have
A) x + y
Here the above equation is the addition of two variables, x and y hence it is not a product of two factors
B) 5(x + y)
Here we have the product of 5 and (x + y), therefore, it is the product of the two factors 5 and (x + y)
C) (x - y)
Here the equation is the difference of two variables, x and y hence it is not a product of two factors
D) xy
Here we have the product of x and y, therefore, it is the product of the two factors x and y.
PQ + QR + RS = 18
PQ = 2x - 6; QR = 1; RS = x - 4
2x - 6 + 1 + x - 4 = 18
3x - 9 = 18
3x = 27
x = 9
Answer: C. 9
3/5 of 30 is 90/5
3/5 of 30 is 18
so when it is 3/5 full then it has 18 gallons
