Answer:
A and C
Step-by-step explanation:
So you know that the area is (b*h)/2
A = (6,6*4,9)/2 = 32,34/2 = 16,17 cm^2
Answer:
The length of the missing segment is 24
Step-by-step explanation:
Given
The figure above
Required
Determine the missing segment
Let the missing segment be represented with x
Given that, there exist parallel lines between the two triangles;
The relationship between the sides of the triangles is as follows;


Cross Multiply

Open bracket


Subtract 15x from both sides



Divide both sides by 5




Hence, the length of the missing segment is 24
Answer:
C
Step-by-step explanation:
Answer:
x = -
, x = 
Step-by-step explanation:
Given
x² - x -
= 0 ( add
to both sides )
x² - x = 
Solve using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2( -
)x +
=
+ 
(x -
)² = 1 ( take the square root of both sides )
x -
= ± 1 ( add
to both sides )
x =
± 1
Thus
x =
- 1 = - 
x =
+ 1 =
