What value could be added to each quadratic expression below to make it a perfect square trinomial? x^2+6x+ x^2+4x+ x^2-20x+

25.2

step-by-step explanation:

2+4x6-8/10= 25.2

the answer is two. hope this !

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
