Final answer:
Bush A had a height of 7.5 in. when planted and grew at a constant rate of 2.5 in. per year. Bush B had a height of 32 in. when planted and grew at a constant rate of 2.5 in. per year. Both A and B are true.
Step-by-step explanation:
To determine which statements are true, let's analyze each statement:
a. Bush A had a height of 7.5 in. when planted and grew at a constant rate of 2.5 in. per year.
b. Bush B had a height of 32 in. when planted and grew at a constant rate of 2.5 in. per year.
c. Bush A and Bush B had the same height when planted.
d. Both A and B are true.
Based on the information given, we can see that statement a is true because it states that Bush A started at a height of 7.5 in. and grew at a constant rate of 2.5 in. per year. Similarly, statement b is true because it states that Bush B started at a height of 32 in. and also grew at a constant rate of 2.5 in. per year. Statement c, however, is not true because the two bushes started at different heights. Therefore, the correct answer is d. Both A and B are true.
