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!
X^2 + 3x - 2 - (2x^2 - x + 6) =
x^2 + 3x - 2 - 2x^2 + x - 6 =
-x^2 + 4x - 8 <===
The answer to the question is
f(x)= 4x - 10
93
Because basically u are adding 3 and then u multiply by 3
