No solution simply because the expression cannot be solved with rational numbers
Answer:
x = 9
Step-by-step explanation:
Sum of all angles of a triangle = 180
63 + 7x + 6x = 180
63 + 13x =180
13x = 180 - 63
13x = 117
x = 117/13
x = 9
It would be
14,494.2 - 282.6 = 14211.6
K= 16
25x^2+40x+16x comes to be (5x+4)^2.
