If you mean (x^3-8x)-(3x-2) then:
<span>1) leave the (x^3-8x) part alone and use the distributive property on the -(3x-2). </span>
<span>2) your question now becomes x^3-8x-3x+2 </span>
<span>3) combine the like terms: x^3-11x+2</span>
Since 20% can be rewritten as 1/5, then we can multiply 18 by 5 to get 90, which is your answer. Hope this helps!
<span>|4x + 12| = 16
As it is in modulus function, it could be either +ve or -ve
4x+12 = 16 OR 4x - 12 = 16
4x = 16-12 OR 4x = 16 + 12
4x = 4 OR 4x = 28
x = 4/4 OR x = 28/4
x = 1 OR x = 7
In short, Your Answer would be either 1 or 7
Hope this helps!</span>
