Find p such that p+1=2x^2, p^2+1=2y^2. Know that p is a prime, x and y are positive integers.

Step-by-step explanation:

Given p + 1 = 2       → 1 = 2 - p

The above equation is quadratic in p.

p = [ -(-1) ± ]  ÷ 2

p =  [1 ± ]  ÷ 2

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .
