Answer:
Ada is correct.
Step-by-step explanation:
Problems with Naman:
Naman is supposed to follow PEMDAS, which is the order of operations, and stands for:
Parenthesis
Exponents (& Roots)
Multiplications
Division
Addition
Subtraction
~
The mistake: Naman moved +6 to the left and added it to the 2 located on the left side of the expression. You cannot do that, as it breaks the law of PEMDAS. On the other hand, Ada did the correct thing, which was to distribute 2 to all terms within the parenthesis (as one term in the parenthesis has a variable, and the other is a constant, meaning that they cannot be combined). This leads to Naman not doing the rest of the question correct.
Next, Ada correctly combined the two constants, which resulted in 0. 0 means nothing, therefore the placeholder is not needed. Therefore, 8x is the final answer.
63 people should be able to fit in because 7 times 9 is 63.

Answer:
9 1/6 yd
Step-by-step explanation:
First, list the lengths of ribbon Laura had or acquired:
8 3/10 yd + 4 3/5 yd. This is equivalent to 8 3/10 yd + 4 6/10 yd, or
12 9/10 yd.
Next, list the lengths of ribbon Laura used:
1 2/5 yd + 2 1/3 yd. The LCD here is 15, so we have 1 6/15 yd + 2 5/15 yd.
Summing up, we get 3 11/15 yd.
Subtract this length from the original 12 9/10 yard with which Laura began:
12 9/10 yd or 12 27/30 yd (LCD is 30)
- 3 11/15 yd or -3 22/30 yd
Subtracting the latter two quantities, we get 9 5/30 yd, or 9 1/6 yd
Answer:
X = 92 degrees
Step-by-step explanation:
the angles of a triangle all add up to 180 degrees, so 40 plus 180-132 = 88
180-88= 92 so X = 92
The prime factorization of 32 is: 2 x 2 x 2 x 2 x 2
The prime factorization of 56 is: 2 x 2 x 2 x 7
