Each of the diagrams below represents a sequence for a tightrope walker. for
each one, explain the sequence and find the length of the unknown trick.

A. x = 3 units

B. r = 6 units

Step-by-step explanation:

A. The length of the whole tightrope is 12 units. It is divided into 4 equal parts, each of length x units.

So,

B. The length of the whole tightrope is units. It is divided into 5  parts. Four of them are equal and each has the length of r units and the fifth part has the length 3 units.

So,

Subtract r:

Subtract 3:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
