If x−2=13, then what is the value of x2−4x+4?

169

Step-by-step explanation:

x−2=13

First find the value of x

x-2+2 = 13+2

x = 15

Now substitute into the expression

x^2 -4x+4

15^2 -4*15+4

225 - 60+4

165+4

169

Given:

x - 2 = 13

x = 15

Put x = 15:

x² - 4x + 4

( x - 2)²

= (15 - 2)²

= 13²

= 169

i think the answer is seven, for if i'm being useless °ω°

step-by-step explanation:

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
