Which quadratic function has one real solution?

0 = 2(x + 7)(x – 5)
0 = (x – 3)(x – 3)the quadratic function f(x) = –x2 – 6x – 8 is graphed.

what are the solutions of the quadratic equation 0 = –x2 – 6x – 8?

2 and –4
–2 and 4
–2 and –4
2 and 4

0 = 2.4(x – 2)(x + 2)
0 = (x – 2)(x – 1)

The pressure exerted on the walls of a container by a gas enclosed within it is directly proportional to the temperature of the gas. if the pressure is 6 pounds per square inch when the temperature is find the pressure exerted when the temperature of the gas is 380 degrees f show work for the

What is the answer to this question? i'm a bit stumped. also how do i do it? 5(x - 4) = 2(x + 5)
