I need help solving this (4a^2+6a+9)(2a-3)​

8a(^3)−27

Step-by-step explanation:

a = 3/2

Step-by-step explanation:

Solve for a over the real numbers:

8 a^3 - 27 = 0

Hint: | Isolate terms with a to the left hand side.

Add 27 to both sides:

8 a^3 = 27

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides by 8:

a^3 = 27/8

Hint: | Elminate the power on the left hand side.

Take cube roots of both sides:

 a = 3/2

in 1995, potato plants were taken into space aboard the space shuttle columbia.

step-by-step explanation:

choose (5, 1.5) and (-1.5,-3.5)

step-by-step explanation:

5 - 1.5 =3.5

-1.5 - (-3.5) = 2

3.5 + 2 =5.5

hope this !
