When Makayla moved into a new house, she planted two trees in her backyard. At the time of planting, Tree A was 19 inches tall and Tree B was 35 inches tall. Each year
thereafter, Tree A grew by 6 inches per year and Tree B grew by 2 inches per year. Let
A represent the height of Tree At years after being planted and let B represent the
height of Tree B t years after being planted. Write an equation for each situation, in
terms of t, and determine the number of years after the trees were planted when both
trees have an equal height.

A=6t+29

B=3t+35

Same height in 4 years

Step-by-step explanation:

A=6t+19

B=2t+35

4 years

Step-by-step explanation:

A-

The tree Orginal Length- 19 inches

Rate the tree grew every year- 6 inches per year

Equation- 6t+19

B-

The tree Orginal Length- 35 inches

Rate the tree grew every year- 2 inches per year

Equation- 2t+35

6(4)+19

24+19

43

2(4)+35

8+35

43

i dont get it. where are the "descriptions"?

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
