Which terms are considered like terms in the following expression?
3n+18-7n+5m


Henry bought a tree sapling that was 6 inches tall. The tree grew half an inch a day. Let d = the number of days the tree has been growing. Which algebraic expression could be used to calculate height of the tree, in inches, after any number of days?
A) d+6
B)1/2D +6
C)1/2 (d+6)
D)6+d +1/2

Answer 1

hi,
the rate at which the tree grows is ----> 1/2 inch a day
the starting height ----->6 inch

so the height of the tree (h)

H = (1/2)D +6

Hope this will help ya !!!

Answer 2

Like terms are terms that have the same variable part.

For example, in the expression
2x + 3y + 5xy - 5x + 7y + 2 - 6y + 10 - 12 xy,
2x and -5x are like terms.
3y, 7y, and -6y are like terms.
5xy and -12xy are like terms.
2 and 10 are like terms.

Answer 3

2 and 10
