Answer:

  3) x = 9

  4) x = 3

Step-by-step explanation:

3) The two short segments are indicated as having a sum equal to the long segment.

  (x +2) +(-5 +x) = 15

  2x = 18 . . . . . . . . . . . . add 3

  x = 9 . . . . . . . . . divide by 2

(This makes the segments be 9+2 = 11 and -5+9 = 4, which total 15.)

__

4) Same deal.

  3x +3 = 4x

  3 = x . . . . . . . . subtract 3x

(This makes the segments be 3(3) = 9 and 4(3) = 12, where 9+3=12.)

Answer:

A = s²

Step-by-step explanation:

A = s² where s represents the side lengths

Since the side lengths of a square are always the same, you can use the formula A = s² for a square instead of using A=l(w)
