Answer:
3x^2 +6x +4
Step-by-step explanation:
5x ^ 2 + 2x + 11 - 7 + 4x - 2x ^ 2
Combine like terms
5x ^ 2- 2x ^ 2 + 2x + 4x + 11 - 7

Answer:
The bill returns to the house of origin.
If the bill advances with amendments, it returns to the house of origin. The house of origin may fail to take action, and the bill “dies.” The legislative body may vote to approve the changes made by the second chamber.

Answer:
- 7.5 ft
- 32.5 ft, 5 ft
- 10.7 ft
Step-by-step explanation:
a) The starting height is h(0) = 7.5 feet, the constant in the quadratic function.
The irrigation system is positioned <u> 7.5 </u> feet above the ground
__
b) The axis of symmetry for quadratic ax^2 +bx +c is x = -b/(2a). For this quadratic, that is x=-10/(2(-1)) = 5. This is the horizontal distance to the point of maximum height. The maximum height is ...
h(5) = (-5 +10)(5) +7.5 = 32.5 . . . feet
The spray reaches a maximum height of <u> 32.5 </u> feet at a horizontal distance of <u> 5 </u> feet from the sprinkler head.
__
c) The maximum distance will be √32.5 + 5 ≈ 10.7 ft.
The spray reaches the ground at about <u> 10.7 </u> feet away.
