There is a difference because in the spring, there may be more days of rain, therefore that would increase the mean for the spring compared to the other days.
Commutative property is "a + b = b + a"
Therefore your answer is 1. 5 + 6 = 6 + 5
Answer:
One time
Step-by-step explanation:
In both the numbers 72 and 78, the place value of 7 is 70.
Hence, 7 in 72 represents one time the value of the 7 in 78.
Answer: We should add the constant 81 to the expression to have a perfect square trinomial.
The perfect square trinomial that would be formed would result from (x + 9)^2.
We can use foil to prove it.
(x + 9)(x + 9)
x^2 + 9x + 9x + 81
x^2 + 18x + 81
81 is the value that must go with 18x in the middle to form the perfect square trinomial.
