A student tried to multiply two polynomials. Their work is shown below, and they made one mistake.
The same mistake appears in the double distribution model and the area model - refer
to the model you prefer.
The mistake is in the first step of distribution:
• Identify the error: what did this student do incorrectly?
• Correct the error: what should they have done instead?

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24
