Solve in(5x+7)=8 round to the nearest thousandth

Ivan

Answer:

$x=\frac{1}{5}$

$x=0.2$

Step-by-step explanation:

$(5x+7)=8$

$5x+7=8$

Subtract 7 from both sides.

$5x+7-7=8-7$

Simplify.

$5x=1$

Divide both sides by 5.

$\frac{5x}{5} =\frac{1}{5}$

Simplify.

$x=\frac{1}{5}$

Decimal form:

0.2

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

$V=L*H*W$

$V=8*1*13$

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