Let d be the number of days and h be the height
h = 13 + 0.6d
Answer: (a) h = 13 + 0.6d
Given height = 0.208m, find d:
0.208m = 20.8 cm
20.8 = 13 + 0.6d
0.6d = 20.8 - 13 = 7.8
d = 7.8 ÷ 0.6 = 13
Answer: (b) 13 days
according to the picture we have:
x.y=4.7
(7)x(7)y=49xy=(49)(4.7)=230.3
Recognize that you must combine "like" terms. 5x^2y and x^2y are "like" terms.
Adding them together, you get 6x^2y.
Now add 2xy^2 to 6x^2y. These are NOT "like" terms, so you end up with
6x^2y+2xy^2 as your final answer. This answer is acceptable as is.
However, you could factor out the common factors: 2xy(3x+y).
