Step-by-step explanation:
step 1. what is 4^2?
step 2. 16.
Answer: =x4+3x3+2x2−4
Step-by-step explanation:
(x2+3x+2)(x2)−4
Distribute:
=(x2)(x2)+(3x)(x2)+(2)(x2)+−4
=x4+3x3+2x2+−4
That's harder than it looks like...
The five in the hundreds place is 10 times grater than the five in the tenths place
|13-6| < x < |13+6|
So the range will be:
7 < x < 19
