Answer:

Option A.

Step-by-step explanation:

The given expression is

$18x+3xy+5y-2(6xy-2y+4)$

We need to find the simplified form of the given expression.

Using distributive property, we get

$18x+3xy+5y-2(6xy)-2(-2y)-2(4)$

$18x+3xy+5y-12xy+4y-8$

Combine like terms.

$18x+(3xy-12xy)+(5y+4y)-8$

$18x-9xy+9y-8$

Therefore, the correct option is A.

If the ball hit the ground it means that its height is equal to 0. In order to find the time after the ball <span>will hit the ground, we need to find the solution of the equation h(x)=0 which is different to 0.

-4.9x^2+21.3x=0
x(-4.9x+21.3)=0
-4.9x+21.3=0
x=21.3/4.9 = 4.3469 seconds</span>
