lutik1710 [3]

The value from the set {3,8,9,14} makes the equation 2n - 5 = 11 true is n = 8

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Given the equation:

2n - 5 = 11

When n = 3:

2(3) - 5 = 1 ≠ 11

When n = 8:

2(8) - 5 = 11

When n = 9:

2(9) - 5 = 13

When n = 14:

2(14) - 5 = 23

The value from the set {3,8,9,14} makes the equation 2n - 5 = 11 true is n = 8

The length of a rectangular prism is 8
Lena [83]
Surface area is:

W=width
L=length
H=height

S=2*(L*W+L*H+W*H)

replacing the values

250=2*(8*W+8*1+W*1)

250=2*(8*W+8+W)

250=2*(9*W+8)

dived each member by 2

125=9W+8

9W=125-8

9W=117

\boxed{\boxed{W=13~unit~of~measure}}

The volume of a rectangular prism is

V=L*H*W

V=8*1*13

\boxed{\boxed{V=104~unit~of~volume}}
