Answer: 7cm
Step-by-step explanation:
The perimeter of a triangle is calculated by adding the length of the 3 sides together. Let the third side be x , then
x + 9 + 6 = 22
x + 15 = 22
Subtract 15 from both sides , that is
x = 22 - 15
x = 7
Therefore : the third side is 7cm
Answer:
7.5
Step-by-step explanation:
15×12=180
180÷24(crayons per box)=7.5 boxes
Answer:
3
x(x^2-3)
4x(x^2+5488)
Step-by-step explanation:
Total length = 111.6 metres
(12.3x7) + 15 + 10.5 = total length
