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

$V=L*H*W$

$V=8*1*13$

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

Dahasolnce [82]

Answer:

The answer is 17

A function is a relation in which each possible input value leads to exactly one output value. For example, we say “the output is a function of the input.”

Step-by-step explanation:

f(-7)=3-2x

3-2(-7)

3 - -14= 17
