Question

Clara is building a triangular garden. She wants the length of the longest side to be three more than twice as long as the length of the shortest side, and the third side will be twelve feet long.
What expression could she write to determine the perimeter of the triangle if s represents the length of the shortest side? (Recall that perimeter is the distance around a shape.)

What is the expression in simplified form?

What is the coefficient of the variable in the simplified expression?

Answer 1

the first anser is: s+(2s+3)+12

second answer : 3s+15

third answer:3

Step-by-step explanation:

dont know why BUT I JUST TOOK THE TEST AND THESE ARE THE RIGHT ANSWER ;))

Answer 2

Perimeter of the garden is 3+2s+12+s

Expression in simplified form will be 15+3s

coefficient of the variable in the simplified expression is 3

How do you find the perimeter of triangle?

• Perimeter of the triangle is sum of all the sides
• s = a+b+c; where a,b,c are sides of the triangle

Let the longest side of the triangle be a

shortest one be s

the other side be b

By the given data, the expression will be a = 3+2s

and also b = 12feet.

Perimeter of the triangle = sum of its sides

= a + b + s

= 3 + 2s + 12 + s

= 15 + 3s

Hence, Perimeter of the garden is 3+2s+12+s

Expression in simplified form will be 15+3s

coefficient of the variable in the simplified expression is 3
