Answer:
standard form of given equation is 5x - 8y = -3
Step-by-step explanation:
Standard form of linear equation is Ax + By = C
First we remove the denominator 8
We multiply the whole equation by 8
So equation becomes
8y = 5x + 3
Now we move 5x to the left hand side, we subtract 5x on both sides
-5x + 8y = 3
Now we remove the negative side from -5x by dividing the whole equation by -1
5x - 8y = -3
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.
