These trees have different heights. The height of the taller tree is 3 feet less than twice the height of the shorter tree. Which expression represents the height of the taller tree in terms of h?
Let h = the height (in feet) of the shorter tree

A. 2h+3
B. 2h-3
C. 3h+2
D. 3h-2

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

The answer is Choice B if you subtract 3 feet from twice the smaller tree you should get the height of the taller tree.

the least common denominator is 40

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".
