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

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

i believe it is b and c. (side note, i got the same computer from k-12 lol i’m in 8th grade and this is my first year, will it get
