Area of triangle is 1/2 times base times height
lets say the base is from x1,y2 to x1,y1 the distance is 6 units
1/2 times 6 times height
from x1,y1 to x3,y3 is 7 units to the right
1/2 times 6 times 7=3 itmes 7=21
area=21 square units or
21 units^2
Answer: Adiya’s method is not correct. To form a perfect square trinomial, the constant must be isolated on one side of the equation. Also, the coefficient of the term with an exponent of 1 on the variable is used to find the constant in the perfect square trinomial. Adiya should first get the 20x term on the same side of the equation as x2. Then she would divide 20 by 2, square it, and add 100 to both sides.
Answer:
where's the equation? your question is missing some parts.
Step-by-step explanation:
the midpoint is the middle point of a line segment
The third side must be greater than the difference of the other 2 sides and less than the sum of the other 2 sides.
5 and 12 SUM = 17
DIFFERENCE = 7
The 3rd side must be greater than 7 and less than 17
So, the third side could be 9 or 11.
