1)3x^3+12x^2-9x=3x

3x^3+12x^2-9x-3x=3x-3x

3x^3+12x^2-12x=0

3x(x^2+4x-4)=0

3x=0 or x^2+4x-4=0

x=0 or x=0.8284271247461903 or x=-4.82842712474619

2)x^2+8x-20=x+10

x^2+8x-20-(x+10)=x+10-(x+10)

x^2+7x-30=0

(x-3)(x+10)=0

x-3=0 or x+10=0

x=3 or x=-10

Answer : x=3 or x=-10

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values
