➷ A) The student did not expand properly for the first expression

B) (3x + 4)(2x + 5) = 6x^2 + 15x + 8x + 20 = 6x^2 +23x + 20

6x^2 + 23x + 20 = 11x + 5

Substitute 2 in:

6(2)^2 + 23(2) + 20 = 90

11(2) + 5 = 27

Lauren is incorrect as both expressions do not equal each other. When 2 is substituted, only the second expression equals 27

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^

Answer:

A) what did the student do wrong, explain why they are incorrect  

B) Demonstrate and explain the correct way to answer the question.  

Lauren says that two expressions 3x+4(2x+5) and 6x +5x +5 are equivalent. Simplify the expressions to determine whether or not Lauren is correct. Substitute a value for x to see if she is right.

<u>3x+8x+20 = 6x+5x+5</u>

<u>11x+20 = 11x+5</u>

<u>She is wrong</u>

Students answer: She is correct because both equal 11x +5. I substituted x=2 and got 27 for both

<u>She is wrong because 27 will be the answer for ' 11x+5' only. The correct method should be </u>

<u>x=-15 </u>

A farmer planted 3 types of trees on 22 acres of land. He planted 48 trees per acre. What is the total of trees the farmer plant
antoniya [11.8K]
Hey there! :D

He planted 48 trees per acre. Ignore the '3 types of trees' part. I think the question is trying to confuse you. Multiply 48 by 22.

48*22= 1056

The farmer has planted 1056 trees.

I hope this helps!

7th grade math help me pleaseee :)
Olegator [25]

Answer:

answer of 2a)

He started with $24 and spent $16. Let a represent his account balance after he bought the notebook and pens. Then

24–16=a

His new account balance is $8.

He has $8 in his account and then he deposited b dollars. His account balance is now $28. Then

8+b=28

His deposited $20 in his account.

He has $28 and spent $34. Let c represent his account balance after he bought the book. Then

28–34=c

His new account balance is -$6.

He started with an account balance of -$6 and paid the debt off so his account balance is 0. If d is the amount money he deposited to pay off his debt, then

−6+d=0

He deposited $6.

answer of 2b)

If he spends more than he has in his account, then we are subtracting a bigger number from a smaller number, and the result is negative. ... The opposite of a positive number is a negative number, so it makes sense to represent his account balance with a negative number when he owes money to the bookstore.

please give me brainliest:))
