Work:
x^2 + 4x - 4 = 8
x^2 +4x -12 = 0
(x + 6) (x - 2) = 0
x = -6 and 2
Answer: first option
I hope this helps!
Answer:
The midpoint is (-2,7)
Step-by-step explanation:
To find the x coordinate of the midpoint, take the x coordinates of the endpoints, add them and divide by 2
(-9+5)/2 = -4/2 =-2
To find the y coordinate of the midpoint, take the y coordinates of the endpoints, add them and divide by 2
(3+11)/2 = 14/2 = 7
The midpoint is (-2,7)
Answer:
Perimeter is 50
Area is 60
Step-by-step explanation:
To get the perimeter, you add all the lengths of the sides together.
To get the area, you do A=hb * b / 2, which is 60
Answer:
Line segment A B is longer than Line segment F D. This is the correct statement from the given statements.
Step-by-step explanation:
Given:
In ΔABC and ΔFDE
Segment AC≅Segment FE
Segment BC≅Segment DE
∠BCA = 72° and ∠DEF = 65°
Now by the property of a Triangle we know that
Side opposite to the greater angle is longer than the side opposite to the smaller angle.
So, Side opposite to the greater angle (∠BCA = 72°) is AB and
The side opposite to the smaller angle (∠DEF = 65°) is FD.
Therefore, side AB is Longer than side FD.
