Answer:
x^2-11x-12
Step-by-step explanation:
I use the box method, which makes a 2x2 box. Then you arrange you numbers based on the equation (show in image)
Then you multiply it out and get the equation
F(x)= x^2+x-12x-12
Simplify your equation and you get
F(x)= x^2-11x-12

Answer:
Step-by-step explanation:
The scale factor (C) is the ratio of corresponding sides of the two pyramids.
The ratio of the areas is the square of the scale factor.
The scale factor is 
.
In the the figure above AC bisects BCD in the quadrilateral, the length of CD will be 6cm.
<h3>How to calculate the value?</h3>
It should be noted that the longer diagonal is a perpendicular bisector of the shorter diagonal.
From the diagram given, the value of AD is 6cm. Therefore, according to the angle bisector theorem, the value of CD is 6cm as they're congruent.
