simplify the expression
0.5x+0.4x-0.1x=
after ea. x squared 3
are you saying everything is like this
0.5x^3 + 0.4^3 - 0.1^3 ?
if so just do it like simple adding and subtracting
.5+.4 is 0.9x^3 -0.1^3
that becomes 0.8x^3
when adding or subtracting variables with exponent keep all exponent the same
yes sorry never done this before
its okay i just wanted to make sure i had your question right
To simplify the expression 0.5x + 0.4x - 0.1x, you can combine the like terms involving "x".
0.5x + 0.4x - 0.1x can be rewritten as (0.5 + 0.4 - 0.1)x.
To evaluate the sum of the coefficients (0.5 + 0.4 - 0.1), follow these steps:
1. Add 0.5 and 0.4: 0.5 + 0.4 = 0.9
2. Subtract 0.1: 0.9 - 0.1 = 0.8
Now substitute the value you found back into the expression:
0.8x
So, the simplified expression is 0.8x.
