Find the polynomial. {5} is the solution set of a) x^2-5x+25=0 b)x^2+10x+25=0 c)x^2-10x+25=0 d)x^2+5x+25=0

option:C

Step-by-step explanation:

A) on putting x=5 in equation we have that the equation is not equal to 0 it gives the value 25. so {5} is not a solution set of A.

B) on putting x=5 in the equation we have the equation is not equal to 0 it gives the value 100. so {5} is not a solution set of B.

C)on putting x=5 in the equation , the equation gives the value 0. so {5} is a solution set of C.

D)on putting x=5 in the equation equation does not give the value zero it gives 75. so {5} is not a solution set for D.

i don't know, but that looks pretty bad. my school passed us unless we failed in all the subjects, but idk abt ur school's rules.

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
