Answer:
4
Step-by-step explanation:
Answer:
181
Step-by-step explanation:
Assuming that the 'x's' all symbolize multiplication, follow these steps.
First, begin with the innermost set of parenthesis: 3x2
This will give you the answer of six, this will now give you the new equation of:
13+[9x(6)-12]x4
Following the rules of PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction), it is inferable that you must multiply before subtracting the twelve.
Perform this step: 9x6 to get the answer of 54.
13+[54-12]x4
Now, as there are still brackets, perform the bracketed information:
54 - 12 = 42
This now gives you: 13+[42]x4
Yet again, following the rules of PEMDAS, you multiply 42x4 then add the result of that to 13.
42x4 = 168
168 + 13 = 181
Therefore, this expression provides the answer of 181.
Hope this helps!
If you multiply out the answers, which is easier, then you can find the correct answer.
The factors need to multiply together to create the original problem, so it's just a matter of plug and chug.
The answer is B.
7 = r^1/2 is the same as saying 7 = square root of r. So, to get rid of the square root sign on the r, you need to square it, and when you do something to one side of the equation, you have to do the same to the other side. So after squaring both sides, you get 49 = r.
