Answer:

AC = BD

2x +10 = 56

x +5 = 28 . . . . . divide by 2

x = 23 . . . . . . . . subtract 5

Answer:

1 = 21 m

2 = 120 cm

3 = 84 cm

4 = 3 km

5 = 10 m

6 = 55 mm

7 = 60 cm

8 = 500 mm

Step-by-step explanation: you see where it says "perimeter = 3s" right? for each question you have to replace "s" with the number given so for the first one it would be 3 x 7. You had to do the same thing with the others but sometimes we get confused in math :D
