Question

A wire is (7x‐3) meters long.The length of(3x+4) meters is cut for use .How much wire is left​

Answer 1

Answer:

Step-by-step explanation:

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

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
