Answer:
y=(4d-8)/(3-c)
Step-by-step explanation:
- -cy + 8 = 4d – 3y
- 3y-cy=4d-8
- y(3-c)=4d-8
- y=(4d-8)/(3-c)

Answer:
square units [one-half x squared square units]
Step-by-step explanation:
As shown in the diagram attached to this response,
Since a square has all sides equal, let the sides of the square be each of <em>a</em> units.
The area, A, of the square = a x a = a²
i.e
A = a² --------------(i)
Now,
The diagonal is x units such that applying Pythagoras rule gives;
x² = a² + a²
x² = 2a²
a² = ----------------(ii)
Substitute the value of a² in equation (ii) into equation (i) to get;
A =
Therefore, the area of the square is square units
