Answer:
Step-by-step explanation:
The ratio of perimeters is the ratio of corresponding sides.
first : second = 8 : 6 = 4 : 3 . . . ratio of perimeters
The ratio of areas is the square of the ratio of linear dimensions.
first : second = 4² : 3² = 16 : 9 . . . ratio of areas
look at the explanation <33
The first figure is similar to the second figure. The ratio would be 4:3
Below.
4x^2 - 4x - 1 = 0
This will not factor.
But 4x^2 - 4x + 1 = 0 will:
= (2x - 1)(2x - 1) = 0
x = 0.5 (*2)
