<span>4(x+5) = 4x +5x
Simplify by distributing and combining like terms
</span>(4)(x)+(4)(5)=4x+5x
4x+20=4x+5x
4x+20=(4x+5x)
4x+20=9x
Subtract 9x from each side
4x+20−9x=9x−9x
5x+20=0
<span />
Subtract 20 from each side
−5x+20−20=0−20
−5x=−20
Divide each side by -5
-5x ÷ -5 = -20 ÷ -5
x = 4
P.S this was actually harder than most algebra problems, so don't beat yourself about it :D<span /><span /><span /><span /><span />
Ok, so if a zero is at r1, then a factor is (x-r1)
since there are no other roots, it must be only taht root
3rd degree so reaise it to the 3rd power
(x-r1)³
and the root is at x=-3
(x-(-3))³
(x+3)³
answer is f(x)=(x+3)³
also could be x³+27 where it factors to one real root and 2 complex roots
B because it is creating it
With would be 3.4
Answer:
I think it's simple sentence
