Answer:
1. +3=5.
2. x = x + 1.
3. x = x + 1.
Step-by-step explanation:
Hope these are good! :) Have a nice day!
Answer:
First one can
Second one can not
Step-by-step explanation:
13² = 5² + 12²
169 = 25 + 144
169 = 169 is a true statement
15² = 11² + 12²
225 = 121 + 144
225 = 265 is a false statement
So, not a right angle triangle
The polynomial

may have solutions which are the divisors of -20, therefore -20 has the following divisors:

.
If x=1, then

,
if x=-1, then

,
if x=2, then

, then x=2 is a solution and you have the first factor (x-2).
If x=-2, then

, then x=-2 is a solution, so you have the second factor (x+2).
Since x-2 and x+2 are two factors of

, then the polynomial

is a divisor of

and dividing the polynomial

by

you obtain

.
