The correct answer would be 4x(2x+3)
5x + 18 + 81 + 4x = 180
Like terms
9x + 99 = 180
9x = 81
X = 9
Hope this helps!
Brainliest is much appreciated
819 as a decimal is
<em> 819.00000</em>
with as many zeros as you want after the decimal point.
If you do anything else to it, then it's a different number,
and it's not 819 anymore.
