Answer:
Step-by-step explanation
I get the same answer you do, but I'm not at all certain I'm correct. I would have done it just as you did letting each y value define the new x value and then putting the - on the left in at the very end.
f(1) = 3
f(3) = -1
f(-1) = 7
But there is a minus in front of the left most f. That would make it - 7

Do you mean 7?
You need to multiply each like term differently ( 1. Coefficient, 2. M term, 3. N term, and 4. O term)
1. The coefficients are 4 and 7, and as you have already solved, that equals to 28.
2. The m terms are (m • m) because there is one m in (4mno) and one m in (mn). m • m would equal to m^2.
3. The n terms are (n • n^2 •n) because there is one n in (4mno), n^2 in (7n^2o^2), and one n in (mn). They would equal n^4.
4. The o term would stay as o^2 as there are not other o terms.
To piece it all together, your answer would be 28m^2n^4o^2, or 28 • m ^2 • n^4 • o^2.
Answer: it will take 0.33 years for the heights to be the same.
Step-by-step explanation:
Let x represent the number of years it will take for both trees to be the same height.
Type A is 7 feet tall and grows at a rate of 2 inches per year. This means that the height of the tree after x years would be
2x + 7
Type B is 2 feet tall and grows at a rate of 17 inches per year. This means that the height of the tree after x years would be
17x + 2
For the heights to be the same, the number of years would be
17x + 2 = 2x + 7
17x - 2x = 7 - 2
15x = 5
x = 5/15
x = 0.33 years
