To find the answer just divide the length of a flower garden by the length of a brick:

11.25 / 0.25 = 45 (that's how many bricks are needed to be put).

There's nothing to round, but you can write it as a decimal to the hundredth place as 45.00.

2x^{3}+30xx^{2} +72x=0 solve using zero product property
Goshia [24]

Answer:

Values of x are: x=0 or x=-3 or x=-12

Step-by-step explanation:

The equation given to solve using zero product property is 2x^3+30x^2+72x=0

Zero property rule states that if ab=0 then a=0 or b=0

Taking x common from the equation:

2x^3+30x^2+72x=0\\x(2x^2+30x+72)=0\\

Applying zero product rule

x(2x^2+30x+72)=0\\x=0 \ or \ 2x^2+30x+72=0

Now, solving 2x^2+30x+72=0

Using quadratic formula to find value of x

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

Putting values

$x=\frac{-30\pm\sqrt{(30)^2-4(2)(72)}}{2(2)}$\\$x=\frac{-30\pm\sqrt{324}}{4}$\\$x=\frac{-30\pm18}{4}$\\$x=\frac{-30+18}{4} \ or \ x=\frac{-30-18}{4}$  \\x=-3 \ or \ x=-12

So, Values of x are: x=0 or x=-3 or x=-12
