Two or zero expresses the possible number of positive real solutions for the given polynomial equation.
Answer: Option D
<u>Step-by-step explanation:</u>
Given equation:
First, we put hit and trial method to find out the one solution. So, if we put x=4 then the above expression will become zero. We can also write the above expression as
We know the formula, 
, make use of this, we get
So, 
Hence, from the above expression, we have three values of x as x= 4, 2.64 and -2.64
Area of a square = length²
A = x²
16 = x²; x = 4
dA/dx = 2x cm²/s
dx/dt = 6 cm/s
Using chain rule:
dA/dt = dA/dx * dx/dt
dA/dt = 2x * 6
dA/dt = 12x
At x = 4,
dA/dt = 12(4) = 48 cm²/s
Answer:
I dont think i dont know this but its 10?
Answer:
the answer is -6,5
Step-by-step explanation:
just look at the left side ( the x axis )first then right(the y axis)

Answer:</h3>
<u>If a rectangle and a triangle have the same area</u>.
Then,
- <u>L × B = 1/2 × B × H</u>
- 10 × 3 = 1/2 × 6 × H
- 30 = 3 × H
- 30/3 = H
- 10 = H
<u>Hence, the height of triangle is 10cm</u>.
