Answer:
f(2a−1)=7a−13
7(2a−1) − 13
14a − 7 − 13
14a − 20
Step-by-step explanation:
replace a with f(2a − 1)
distribute the bracket
combine -7 and -13 because they are the like terms here.
15ft because 12x.25=3 so 3ft is 25% of the 12ft, add the 3+12=15
7a + 6c + 9a - 15c
-- Look for all the 'a's 7a, 9a
-- Addum up 16a
-- Look for all the 'c's 6c, -15c
-- Addum up -9c
-- Write the results 16a - 9c
Answer:
Since the sum is same, the associative property of addition holds true. Therefore, it can be concluded that the grouping of numbers in any order does not change the sum. Example 6: Consider the algebraic expression, .
