Y = - 5
I hope this helps. :)
Answer:
1. The first problem is wrong, it should be 0.5(3(15) + 2(20)) because the parentheses make sure that every purchased item is being divided by 2 (multiplying by 0.5 is the same as dividing by 2)
2. The second problem is partially correct. The first two answers you have checked are correct, but the last one is wrong. The third answer should be 6 + 12 instead because that's just a simplified version of 2(3) + 6(2), meaning they are equal
3. I cannot read your answers in the "Why or Why Not" column in the third problem, but the answers you gave in the "Evaluate" and "Does It Work?" columns are all correct.
To find the mean, aka average, we must add all the values of the table, then divide that sum by the number of values
Hi
9k^2 + 24k + 16
= ( 3k + 4)(3k + 4)
Good luck
