175m^2
I got the by multiplying 1/2, by the base (14), by the height (25).
1/2 * 14 * 25
Hey there!
x^2 + 4x = 12
SUBTRACT 12 to BOTH SIDES
x^2 + 4x - 12 = 12 - 12
SIMPLIFY IT
x^2 + 4x - 12 = 0
FACTOR the LEFT SIDE of your EQUATION
(x - 2)(x + 6) = 0
• EQUATION #1: x - 2 = 0
OR
• EQUATION #2: x + 6 = 0
SIMPLIFY IT
• EQUATION #1 answer: x = 2
OR
• EQUATION #2 answer: x = -6
OVERALL ANSWER: x = 2 or x = -6
YOUR ANSWER: x = 2 (Option A.)
Good luck on your assignment and enjoy your day!

Step-by-step explanation:
From similar triangles, see diagram in attachment
We solve for to obtain,
The formula for calculating the volume of a cone is
We substitute the value of to obtain,
This implies that,
We now differentiate both sides with respect to to get,
We were given that water is drained out of the tank at a rate of
This implies that .
Since we want to determine the rate at which the depth of the water is changing at the instance when the water in the tank is 8cm deep, it means .
We substitute this values to obtain,
