Question

is 3x + 5x and 15x equivalent? why or why not?? ​( PLEASE ANSWER IN FULL AND COMPLETE SENTENCES, NO TROLLS, YES OR NO?? and WHY)​

Answer 1

Answer:

it's not equal

Step-by-step explanation:

for an example we can take x=2 :

then (3×2) + (5×2) = 6+10 = 16

but here 15×2 = 30 , not 16

if we take 'x' as common factor then:

x(3+5) = x(8)

and 2×8 = 16
