Question

a wire is (7x-4)cm long a leghnth of (5x-8) is cut for use how much is left?
please answer correctly step by step​

Answer 1

Answer:

length of wire =(7x−3)m

Step-by-step explanation:

Given,

length of wire =(7x−3)m

and wire cut for use has length =(3x−4)m

Left wire =(7x−3)−(3x−4)=(4x+1)m

(b) Left wire =(4x+1)m

Perimeter of equilateral triangle = Length of wire left

⇒ 3×side=4x+1

⇒ side=3(4x+1)=31(4x+1)m
