Answer:
reflection in the y- axis
Step-by-step explanation:
Under a reflection in the y- axis
a point (x, y ) → (- x, y )
Note the x- coordinate is opposite in sign and the y- coordinate remains unchanged.
Thus
(- 4, - 6 ) → (4, - 6 )
(- 6, 4 ) → (6, 4 )
The endpoints have been reflected in the y- axis
Answer:
2√10
Step-by-step explanation:
Given the following data;
Area of square = 40
Mathematically, the area of a square is calculated by using the formula;
Area, A = s²
Where;
s is the length of sides of a square.
Substituting into the formula, we have;
40 = s²
s = √40
s = √4 * √10
s = 2 * √10
s = 2√10
