Answer:

\left(6x^3-5x^2+3x-5\right)+\left(8x^4+3x^3+5x^2+x+4\right)

Combine like terms

=8x^4+6x^3+3x^3-5x^2+5x^2+3x+x-5+4

Add: -5x²+5x²=0

=8x^4+6x^3+3x^3+3x+x-5+4

Now add 6x³+3x³=9x³

=8x^4+9x^3+3x+x-5+4

Add like terms 3x +x=4x

=8x^4+9x^3+4x-5+4

Now add -5+4=-1

=8x^4+9x^3+4x-1

Decrease £43 by 29% what’s the answer
borishaifa [10]

Answer:

30.53

Step-by-step explanation:

First you must find what 29% of 43 is, in order to do this we must multiply 43 by 29%

43*29% or 43*.29 is 12.47

This means that 29% of 43 is equal to 12.47

So decreasing 43 by 29% would be the same as decreasing 43 by 12.47

43-12.47=30.53
