Answer:
Explanation:
Let's denote the height of the shorter plant as '7x', where 'x' is a constant, and the height of the taller plant as '9x'. We can set up an equation based on the given information:
9x = 7x + 26
Simplifying, we get:
2x = 26
Dividing both sides by 2, we get:
x = 13
Therefore, the height of the shorter plant is 7x = 7(13) = 91cm, and the height of the taller plant is 9x = 9(13) = 117cm.
Their total height is:
91cm + 117cm = 208cm
