All triangles in this shape have same area as they have same base length and height length.
- area of triangle: 1/2 * base * height
Here the base is 4.2 cm and height is 2.5 cm for all the given triangles.
As a result, we can say that the area of
A,
B,
C are equal.
Answer:
-1 and -3
-5 and 1
-7 and 3
they all equal -4.
Step-by-step explanation:
-3|2x + 6| = -12
|2x + 6| = -12/-3 = 4
2x + 6 = 4 and 2x + 6 = -4
2x = 4 - 6 = -2 and 2x = -4 - 6 = -10
x = -2/2 = -1 and x = -10/2 = -5
x = -1 and x = -5
