Question

A wire is (7x-3) metres long. A length of (3x-4) metres is cut for use .Now answer the following questions:-
a)How much wire is left ?
b)If this left out wire is used for making an equilateral triangle,what is the length of each side of the triangle formed?

​

Answer 1

Answer:

A) total length of wire=(7x-3)

length of wire cut=(3x-4)

7x-3-(3x-4)

=7x-3-3x+4

=7x-3x-3+4

=4x+1

4x+1 meter is the length of wire that is left

B) Now equilateral triangle has all three sides equal

therefore

4x=1/3 meter will be the length of each side of the equilateral triangle formed
