To get roots of 13 and -3 the simplified equation will have to look like this.
(X-13)(X+3)=0
So if we multiply this out with foil method we get this:
X^2 -10X -39
So the answer is A
Answer:
$16.6
Step-by-step explanation:
x is the price of each CD before tax
so 3x + 3.60 = 53.40
3x = 53.40 - 3.60 = 49.80
x = 49.80/3 = 16.6
Range I think I may be wrong ?
To find the zero you must set each factor equal to zero and solve for for x like so...
Factor (x - 7)
x - 7 = 0
x = 7
Factor (x + 4)
x + 4 = 0
x = -4
Factor (3x - 2)
3x - 2 = 0
3x = 2
x = 
All the zeros are:
-4, , 7

Answer:
54 sq units
Step-by-step explanation:
The triangle at the top (FAB) has a base of 10 and a height of 3. Area of triangle is 1/2bh so 1/2(10 * 3) = 1/2 * 30 = 15 sq units
If you cut off the triangle you have a trapezoid, EBCD. A trapezoid is (b1 + b2)/2 * h, so (6 + 7)/2 * 6 = 13/2 * 6 = 6.5 * 6 = 39 sq units
Add them together: 15 + 39 = 54 sq units
