A rectangular swimming pool that is 10 ft wide by 16 ft long is surrounded by a cement sidewalk of uniform width. If the area of

cestrela7 [59]

Let 's x the width of the sidewalk.

Area of the swimming pool= 10*16=160 (ft²)
Area of the sideway+the swimming pool= (16+2x)*(10+2x) =160+155

==>160+20x+32x+4x²=160+155
==>4x²+52x-155=0
Δ=52²+4*4*155=5184=72²
==>x=(-52+72)/2=5/2 or x=a negative to exclude.

Width of the sideway=5/2 ft
so tell me if i helped

Answer:

The given equation will have two roots as +5i and -5i

Step-by-step explanation:

Shasta claimed that the equation x^2+25=0 can be solved by using its factored form of (x+5i)^2=0, and that -5i is the only zero for this function

The given equation is $x^2+25 =0$
