Answer:
-12x+29
Step-by-step explanation:
= -2(x+3) – 5(2x – 7)
= -2(x)+(-2)(3)-5(2x)-5(-7)
= -2x-6-10x+35
= -2x-10x-6+35
= -12x+29
Answer:
12
Step-by-step explanation:
x^2-2x+4 replace -2 for x
-2^2-2(-2)+4
4+4+4

Answer:
a. 
Step-by-step explanation:
The given equation is;

To solve by the x-intercept method we need to graph the corresponding function using a graphing calculator or software.
The corresponding function is

The solution to
is where the graph touches the x-axis.
We can see from the graph that; the x-intercepts are;
(-1,0),(3,0) and (6,0).
Therefore the real solutions are:
