Two sides of a triangle have the same length. The third side measures 7m less than twice the common length. The perimeter of the triangle is 17m. What are the lengths of the three sides? What is the length of the two sides that have the same length?

Step-by-step explanation:

I am pretty sure your answer is 3

2 sides=5 lonely side =7

Step-by-step explanation:

if the full perimeter is 17 and one side is just 7 then you can subtract 7 from 17 and get ten so then you can divide ten by two and get 5 for both sides.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

10 b/c 5*2 =10
