Rewrite the quadratic function in intercept or factored form y=x^2+7x+10
1 answer:
Answer:
Step-by-step explanation:
1. You have the following the quadratic equation given in the problem above:
2. To factor the quadratic function, you must find two number that when you add them you obtain 7 and when you multiply them you obtain 10. These numbers would be 2 and 5.
3. Therefore, keeping this on mind, you can rewrite the function in the following intercept form:

Answer:
74.1 units²
Step-by-step explanation:
Area of the trapezoid shown = ½×(AD + BC)×BE
Use distance formula, to find AD, BC, and BE.
✍️Distance between A(-9, 4) and D(9, 1):
(nearest tenth)
✍️Distance between B(-4, -3) and C(2, -4):
(nearest tenth)
✍️Distance between B(-4, -3) and E(-3, 3):
(nearest tenth)
✔️Area of the trapezoid:
Area = ½×(AD + BC)×BE
Plug in the values into the formula
Area = ½×(18.2 + 6.1)×6.1
Area = ½×(24.3)×6.1
Area = 74.115 ≈ 74.1 units² (nearest tenth)
