Answer: Distributivo
Step-by-step explanation:
2*3 = 6
2 * x = 2x
Therefore:
2(3+x) = 6 + 2x
Answer:
It is 25 units
Step-by-step explanation:
The triangles are equal
x = 180° - 67° - 52°
x = 61°
So, the value of x is 61°

Step-by-step explanation:
The given function is f(x) = 9·x² + 54·x - 66
The extremum of the function are found as follows;
d(f(x))/dx = 0 = d(9·x² + 54·x - 66)/dx = 18·x + 54
∴ 18·x + 54 = 0 at the maximum or minimum points
x = -54/18 = -3
Given that d²(f(x))/dx² = 18 > 0. x = -3 is a minimum point
Given that the function is a quadratic function, we have;
1) Points to the left of x = -3 are decreasing
2) Points to the right of x = -3 are increasing.
Either the first or the third choice is correct. We can't tell which one without seeing the rest of the words ... the ones that are cut out of the picture.
