Step-by-step explanation:
h/w=9/16
h/42=9/16
h=42(9)/16
h=23.625
It will be 3/8 in less than 24 in, but 24 was a good guess. :)
To find how many times the quadratic function intersects the x-axis, set y = 0
y = x^2+10x+25
0 = x^2+10x+25
Factor the right hand side
0 = (x+5)(x+5)
x + 5 = 0
x = - 5
Therefore, the quadratic equation intersects the x-axis at one point (x = -5)
