Answer:
-5x^2 +x
Step-by-step explanation:
x(x-2)-3x(2x-1)
Distribute
x^2 -2x -6x^2 +3x
Combine like terms
-5x^2 +x
Answer: c= $( 5 x 5.20)
Step-by-step explanation:
Given: Total people =5
Money paid by each person = $5.20
Total cost of the sundae = (Number of people ) x (Money paid by each person)
Total cost of sunday : c= 5 x ($5.20)
i.e.Total cost of sunday = $(5 x 5.20)
i.e.Total cost of sunday = $ 26
Hence, the required equation to represent the total cost (c) of the sundae:
c= $( 5 x 5.20)
We will use PEMDAS rule to simplify the given expression.
PEMDAS rule is given by:
P
-Parentheses first
E
-Exponents (ie Powers and Square Roots, etc.)
MD-Multiplication and Division (left-to-right)
AS
-Addition and Subtraction (left-to-right)

Step 1: P-parenthesis first.
(3-9) is -6
√16 -1 = 4-1 =3
So new expression becomes : 
Step 2:
Multiplying (-3)*(-6)*2
We get +36
So new expression becomes : 25 +36
Step 3: Addition
Adding 25 and 36 we get 61
So final answer is 61 .
