Mr. Carlevato and Mr. Burrows get into a debate about two different expressions. · Mr. Carlevato says "2(2x + 3) is equal to 4x
ruslelena [56]

Answer:

Yes, the same answer is obtained.

Step-by-step explanation:

According to Mr. Carlevato, 2(2x+3) is equal to 4x+6. However, 2(2x+3) is not equal to 4x+6 according to Mr. Burrows.

Put x=5 in 2(2x+3)

2[2(5)+3]=2(10+3)=2(13)=26

Put x=5 in 4x+6

4x+6=4(5)+6=20+6=26

Therefore,

2(2x+3)=4x+6

Yes, the same answer is obtained.
