Answer:
<u>52 cm</u>
Step-by-step explanation:
1st piece (from bottom) = 67 cm
15th piece = 32 cm
a = 67
a₁₅ = a + 14d = 32
14d = 32 - 67
d = -35/14
d =-5/2
d = -2.5
a₇ = a + 6d
= 67 + 6(-2.5)
= 67 - 15
= <u>52 cm</u>

x = 3/2
Step-by-step explanation:
4X + 1/2(4X +6)=12
Distribute
4x+2x+3 = 12
6x +3 = 12
Subtract 3 from each side
6x+3-3 = 12 -3
6x = 9
Divide each side by 6
6x/6 = 9/6
x = 3/2
