I believe the answer is A.
Answer:
12-17
Step-by-step explanation:
this is right. trust (:
There are 25 students in the class
Rectangle A=bh=4 x 3
Triangle A=1/2bh=1/2 x4 x3
The area of the figure
12+6=18
The second sentence above helps with this answer. The y-intercept is the initial height of the plant before any documentation of time and growth was collected. Since the plant was initially 5 cm high, we can use it as a starting point for the data. For example, using x=0 indicates 0 day and if we substitute it in you will see that we are left with a solution of 5. This will let those reading the data to understand that the plant was already at 5 cm when the experiment began.
