The mirror is in a shape of a pentagon
The equation is a reduction
it’s scale factor is 1/ 2
an algebraic representation for the dilation is written as (x, y) -> (kx, ky), with k being the variable for the scale factor
(2, 6) -> (1/ 2 • 2, 1/ 2 • 6)
3x - 5 = 10 or 3 × 5 - 5 = 10
y ÷ x - 4 = 14 or 36 ÷ 2 - 4 = 14
Number 5. 7776 in squared
