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>
Step-by-step explanation:
Answer:
they're equal
Step-by-step explanation:
1 liter is equal to 1,000 ml, so 5 liters is equal to 5,000 ml
Answer:

Step-by-step explanation:
Given:

Solving for
:

Formula for volume L x W x H
We got them all.
So, 30 x 15 = 450.
450 x 12 = 5400
The aquarium is 5400^2 inches
I believe the answer is about a 60% chance. I hope this helps!
