The side length of a square is represented by the expression n - 1.5. which are equivalent expressions for the perimeter of the square?

a
n + n + n + n - 1.5 - 1.5 - 1.5 - 1.5

b
2(n - 1.5) + 2(n - 1.5)

c
2n - 1.5

d
4n - 1.5

e
2(n - 1.5)

f
4(n - 1.5)

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
