Answer:2 and 4 and the second one is 7 and 8
Step-by-step explanation:
40-30=10 minutes more per day x 31 days = 310minutes in a month with 31 days.
The answer would be 25/9 as a improper fraction
N; n+1; n+2 - 3 consecutive numbers
n(n + 1) = (n + 2)² - 19 |use a(b + c) = ab + ac and (a + b)² = a² + 2ab + b²
n² + n = n² + 4n + 4 - 19 |subtract n² from both sides
n = 4n - 15 |subtract 4n from both sides
-3n = -15 |divide both sides by (-3)
n = 5
n + 1 = 5 + 1 = 6
n + 2 = 5 + 2 = 7
Answer: 5; 6; 7.
Answer:
i'm guessing you're asking which expression is the same as 7(x+4)
i don't know what the other numbers listed are suppose to mean, but when expanded, 7(x+4)=7x+28
anything added together, multiplied together, etc, that equals 7x+28 is your answer
