What term is used to describe the idea that people try to control what others think about them?

Peer pressure or something like that I forgot it but yea

Explanation:Someone is doing something and they call you a chicken for not doing it and you do it (hope I helped)

The length of the model = 2x+1

The width of the model = x+1

The total surface area given = 28 unit²

so the equation forms

(x+1)(2x+1) = 28unit²

x(2x+1)+1(2x+1) = 28unit²

2x²+x+2x+1 =28 unit²

2x²+3x+1 = 28 unit²

2x²+3x = 27 unit²

2x²+3x-27 = 0

now the equation is in the form of ax²+bx+c = 0

so if a = 2 ,b = 3 and c = -27

then we know ax²+bx+c= 0

so x = -b±√b²-4ac/2a

so here x = -3±√9+216/4

x= -3±√255/4

so x₁ = -3+√255/4 = 3.24 units

and x₂ = -3-√255/4 = -4.74 units

so x{3.24,-4.74}units (ans)

Hope it helps
