Answer:
the value of c= 25
Explanation:
The algebra tiles represent the perfect square trinomial x^2 + 10x + c
To get perfect square trinomial we apply completing the square method
In completing the square method we take half of the coefficient of middle term and then square it
10/2= 5
5^2 = 25
25 make the expression a perfect square trinomial
x^2 + 10x+ 25
so , the value of c= 25
