True
4x^2 -16x +16 = (2x -4)^2
A = 2x
B = 4
The total amount of the resulting mixture can be calculated by adding up the volume of the given substances assuming that volume addition is applicable given the properties of the fluids used.
That is,
T = 6 quarts + 10 quarts = 16 quarts
The total volume of the resulting mixture is 16.
Then, we do the component (antifreeze) balance by adding up the resulting antifreeze from the substances to the total. We let x be the percentage of antifreeze in the final mixture.
6(0.52) + 10(0.32) = 16(x)
The value of x from the equation is 0.395.
Therefore, the answer to this item is 39.5%.
The answer is 360 -15 times -24 equals 360
Step-by-step explanation:
We know that
cos 2x = 2cos²x - 1
So we have
Substituting 
The answer is 12.58 rounded up it would be 13 so the correct answer is A
