<h3><em><u>A. 4xy-16</u></em></h3>

<em><u>=4(xy−4)</u></em>

<h3 /><h3><em><u>B. xy+2xy-x</u></em></h3>

<em><u>3xy−x</u></em>

<em><u>=x(3y−1)</u></em>

<h3><em><u>C. 2x²-18x+12</u></em></h3>

<em><u>2x²</u></em><em><u>−18x+12</u></em>

<em><u>=2(</u></em><em><u>x²</u></em><em><u>−9x+6)</u></em>

<h3><em><u>D. 5xy+20x-9y-36</u></em></h3>

<em><u>5xy+20x−9y−36</u></em>

<em><u>=(y+4)(5x−9)</u></em>

Why is the number that satisfies this equation not a real number?<br> x^2=--1
Yuri [45]

Answer:

I assume that says x^2=-1, but that is the case because when we square a number, we can NEVER get a negative number. The smallest square we can get is 0. 1^2 is 1, and no real number squared gives us a negative number.

Line segment AB has endpoints A(7.5, 4.2) and B(2.3, 5.4). Find the coordinates of the point that divides the line segment direc
galben [10]
Given a line with endpoints A(x_1,\, y_1) and B(x_2,\, y_2), the <span>coordinates of the point that divides the line segment directed from A to B in the ratio of m : n is given by</span>

(x,\, y)=\left( \frac{n(x_1)+m(x_2)}{m+n} ,\,  \frac{m(y_1)+n(y_2)}{m+n} \right)

Given that l<span>ine segment AB has endpoints A(7.5, 4.2) and B(2.3, 5.4). the coordinates of the point that divides the line segment directed from A to B in the ratio of 1 : 3 is given by

(x,\, y)=\left( \frac{3(7.5)+2.3}{1+3},\,  \frac{3(4.2)+5.4}{1+3} \right) \\  \\ =\left( \frac{22.5+2.3}{4} ,\,  \frac{12.6+5.4}{4} \right)=\left( \frac{24.8}{4} ,\, \frac{18}{4}\right) \\  \\ =(6.2,\, 4.5)</span>
