Clara states that r² + 5r + 3r is an equivalent expression to 9r. Why is Clara's statement incorrect? You need to substitute using r=1, r=2 and r=4 in both expressions to see if they are equivalent. Then read choices carefully. CHOOSE ALL THAT APPLY. A. The expression r² + 5r + 3r simplifies to r²+8, which is not equivalent to 9r.

B. When you substitute 1 for r in both expressions, r² + 5r + 3r has a value of 10 and 9r has a value of 9. These values are not equal.

C. The expression r² + 5r + 3r simplifies to 10r, which is not equivalent to 9r.

D. When you substitute 2 for r in both expressions, r² + 5r + 3r has a value of 20 and 9r has a value of 18. These values are not equal.

E. When you substitute 4 for r in both expressions, r² + 5r + 3r has a value of 48 and 9r has a value of 36.

F. The expression r² + 5r + 3r simplifies to r(r+8), which is not equivalent to 9r.
