2. Factors of x^2 - 5x + 6 are (x-2)(x-3) so the answer would be 2) (x-2)
4. Factors of x^2 + x - 20.  First find the factors of 20.  1, 20; 2, 10, 4, 5.  Then find which factors would equal "b" in the equation or in this instance "1".  This would be 4 & 5.  Since "c" is a negative 20, one of the factors will be a negative.  So, the factors of this trinomial are (x-4)(x+5).  
6.  Factors of n^2 + 3n - 54.  First find the factors of 54.  1, 54; 2, 27; 3, 18; 6, 9.  Then find which of these factors would equal 3.  This would be 6, 9.  Since 54 is negative, and 3 is positive, the larger of the two factors will be the positive # and the smaller will be the negative #.  So, the factors of this trinomial are (x-6)(x+9).

Hi,
Following the rules of PEMDAS you first subtract in the parentheses. 
(5-2)=3
Then multiply the parentheses.
(3)(-6)=-18
Solve the exponent.
-4^2=16
Then you add -18 and 16 to get -2. 
So the answer is B.-2.
I hope this helps.

Which of the following represents the equation of the line passing through (-4,5)
Sergio [31]

Answer:

Answer: y=2x+13.

Step-by-step explanation:

Your input: find the equation of the line perpendicular to the line y=5/2−x/2 passing through the point (−4,5).

The equation of the line in the slope-intercept form is y=5/2−x/2.

The slope of the perpendicular line is negative inverse: m=2.

So, the equation of the perpendicular line is y=2x+a.

To find a, we use the fact that the line should pass through the given point: 5=(2)⋅(−4)+a.

Thus, a=13.

Therefore, the equation of the line is y=2x+13.

Answer: y=2x+13.

The side of a square is Two raised to the seven halves power inches. Using the area formula A = s2, determine the area of the sq
AlladinOne [14]

Answer:

Step-by-step explanation:

Area of a square = s²

s is the side length of the square

Given

s = 2^{7 1/2}

s = 2^15/2

Area = ( 2^15/2)²

Area = 2^15

Hence two area of the square is 2^15 inches
