Hello ! You’re answer will be 2x^2+7x-4.
Hope this helps ! :)
This is the expression for "three more than the square of the number"

(There's really no equation to do, unless your question is truncated.)
The value of the functions f(x) and g(x) will be √(4x + 3) and √2. Then the correct option is B.
<h3>What is a function?</h3>
A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
If (f g)(x) = h(x) such that h(x) = √(8x + 6). Then we have
(f g)(x) = h(x)
f(x) · g(x) = h(x)
Then put the value of h(x), then we have
f(x) · g(x) = √(8x + 6)
f(x) · g(x) = √2(4x + 3)
f(x) · g(x) = √(4x + 3) × √2
Thus, the value of the functions f(x) and g(x) will be √(4x + 3) and √2.
Then the correct option is B.

(a) Water balloon 1 has height at time 

and water balloon 2 has height

Both water balloons are moving straight downward, so their distance is equal to

(b) When both water balloons are at the same height, we have
. So you could set both quadratic expressions equal to each other and solve for
. Or you can use the fact that, when they're at the same height, the distance between them is 0. So using the expression from part (a), we have

or 1.75 seconds after being thrown/dropped.
At this time, they are both at a height of
:

feet.
(c) The second and fourth statements are true.
