There equivalent
Step-by-step explanation:
x+x+x+x=4x:
count the number of x's they equal 4 so it would be 4x
x+5=5x
you have 5 x's it would equal 5x
X = shorter piece
y = longer piece = 5x
shorter piece + longer piece = 60
x + 5x = 60
6x = 60
x = 60/6
x = 10 in. <== shorter piece
y = 5x
y = 5(10)
y = 50 in. <== longer piece
