180 + 30x = 60 + 50x
⇒ 20x = 120
⇒ x = 6 minutes

Answer: The measure of AC is 32.
Explanation:
It is given that the Points B, D, and F are midpoints of the sides of ΔACE. EC = 38 and DF = 16.
The midpoint theorem states that the if a line segments connecting two midpoints then the line is parallel to the third side and it's length is half of the third side.
Since F and D are midpoints of AE and EC respectively.
So by midpoint theorem length of AC is twice of DF.
Therefore, the length of AC is 32.

Answer:
x² - 9
Step-by-step explanation:
: Sum of the zeroes (α + β) = 0 and one zero (α) = 3 . On substituting β = - 3 in eq 1 . Hence, the required quadratic polynomial is x² - 9
