Answer:
7
Step-by-step explanation:
This problem deals with order of operations. If you solve the problem from left to right, you will get an incorrect answer. Instead recall PEMDAS.
Parentheses first
Exponents
Multiplication and Division (left-to-right)
Addition and Subtraction (left-to-right)
We start with the division, as there are no parentheses or exponents. 3÷3=1.
Now we can replace the 3÷3 with a 1 in the expression.
7-1.0+1
Since we only have addition and subtraction left, we now proceed from left to right.
7-1.0=6, and 6+1=7.
or
7-1.0+1=7.
Therefore, the answer is 7.
Answer:
D.
Step-by-step explanation:
The point-slope form of a line is given by:
The line given to us has equation; .
The slope of this line is -4. The of the line perpendicular to this line is the negative reciprocal of the slope of the given line.
Our slope of interest is therefore;
Since the point goes through (-2,7), we have .
We plug in the slope and the point into the point-slope formula to obain;
The required equation is:
(a+b)(a²-ab+b²)
(2x+1)((2x)²-(2x)(1)+1²)
(2x+1)(4x²-2x+1)
