The given quadratic equation has no real solutions.
Given quadratic equation is:
The discriminant(D) of a quadratic equation tells about the nature of roots.
If , the roots of the quadratic equation will be real and distinct.
If , the roots of the quadratic equation will be real and equal.
If , the roots of the quadratic equation will be imaginary.
Given that the quadratic has a discriminant value of -16.
So, the roots of the given quadratic equation will be imaginary.
So, the given quadratic equation has zero real solutions.
Hence, the given quadratic equation has no real solutions.

the complete question in the attached figure
<span>we have to find the surface area first</span>
<span>the area of the base is A1------- > 5*2=10 ft</span>²
A2 (area of two rectangles faces)---------- > 2*3+2*4=14 ft²
A3 (area of the two triangles faces)
base of triangle------------ > 5---------- > (x)+(x-5)
x²+h²=3² ------------ > h²=9-x²
(5-x)²+h²=4²----------- > h²=16-(5-x)²
9-x²=16-(5-x)²-------------- >9-x²=16-25-10x-x²----------------- > x=1.8
h²=9-(1.8)²------------ > h=2.4 ft
A3= (5*2.4)*2/2=12 ft²
the surface area total=A1+A2+A3=10+14+12=36 ft²
if $0.22 ------------------------ > 1 ft²
X----------------------------------> 36 ft²
X=36*.22=$7.92
the answer is $7.92
