4(x-3) and 4x-3 (2n) ^ 3 and 8n^3 (6x-3)/(3) and 2x tell if the expressions are equivalent

well if you know distributive property.....

4(x-3) = (4)(x) + (4)(3) = 4x-12

and False not equivalent

These expressions are equivalent

Last one.... False not equivalent

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

94

step-by-step explanation:
