An artist is creating a sculpture using bendable metal
rods of equal length. one rod is formed into the
shape of a square and another rod into the shape of
an equilateral triangle. if each side of the triangle is
2 inches longer than each side of the square, how
long, in inches, is each rod?
a) 16
b) 18
c) 24
d) 30
( explain and show your work )

Option C 24 in

Step-by-step explanation:

Let

x> the length of each rod

b > the length side of the square

a > the length side of the equilateral triangle

we know that

The perimeter of the square is 4b

The perimeter of equilateral triangle is 3a

so

2x=4b+3a > equation A

4b=3a > equation B

a=b+2 > equation C

Substitute equation C in equation B and solve for b

4b=3(b+2)

4b=3b+6

4b-3b=6

b=6 in

Find the value of a

a=b+2 > a=6+2=8 in

Find the value of x

x=4b  or x=3a

x=4(6)=24 in

therefore

The length of each rod is 24 inches

10

step-by-step explanation:

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
