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!
Answer:
a. 29
b. 9.1
Step-by-step explanation:
General = The perimeter is all the sides added togther.
a. x is given to you, so you just add all the numbers.
b. Now the perimeter is given, but not x. So add the numbers you can see. That would be 9+6.5+4.7= 20.2
So something + 20.2 has to equal 29.3
29.3 - 20.2 = 9.1.
I did not answer c. because I'm not very confident that my answer would be right. With my explainaion I hope you can figure it out easily enough. Good Luck!

Answer:
395.5917959
Step-by-step explanation:
parallelogram area is 15 x 12
one half circle is 9^2
/2
the other is 7.5^2/2
add all together
-2m - 5m - 8 = 3 + (-7) + m
-7m - 8 = -4 + m
or
-7m - 8 = m - 4
or
-8 - 7m = -4 + m
Answer
2) -7m - 8 = m - 4
4) m - 4 = -7m - 8
5) -8 - 7m = -4 + m
