(f + g)(x) = 7x + 6 + 4x² = 4x² + 7x + 6
The notation given means to add the rules of f(x) and g(x), and since there are no like terms, your answer is 4x² + 7x + 6
Answer:15
Step-by-step explanation:
x=180-(110+55)=15
Answer:
When you change from 100% to 200%, the new image on your screen is an enlargement of the previous image with a scale factor of 2.
For quadrilaterals inscribed in a circle, the opposite angles must sum up to 180 degrees. Therefore, angle I + angle D should add up to 180
45 + angle D = 180
angle D = 135 degrees.
(Similarly, angles L & W would also add up to 180, and angle L = 81 degrees.)
If you were to round it upwards, it would be 12. :)
