What is the surface area of the rectangular pyramid shown?

59.5 cm2
63 cm2
75.5 cm2
99 cm2

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
