Answer:
it is C! if I were to write t<6 on a number line it would be open circle above 6 and going to the left since it is smaller than 6!
The area of the triangle ABC is 207.5 square units.
Explanation:
The measurements of the sides of the triangle are
,
and 
We need to determine the area of the triangle ABC.
<u>Area of the triangle:</u>
The area of the triangle can be determined using the formula,

where
,
and 
Substituting these values in the above formula, we get,

Simplifying the values, we get,



Rounding off to the nearest tenth, we get,
Thus, the area of the triangle ABC is 207.5 square units.
Answer:
x = -1 ± √3
Step-by-step explanation:
3x² − 2x − 1 = x² − 6x + 3
Move everything to one side.
2x² + 4x − 4 = 0
Divide by 2.
x² + 2x − 2 = 0
Solve with quadratic formula, or by completing the square.
x² + 2x = 2
x² + 2x + 1 = 3
(x + 1)² = 3
x + 1 = ±√3
x = -1 ± √3
