Length=3*width
area=12
3W*W=12
w^2=4
w=2
l=6

perimeter=2(l+w)
                =2(2+6)
                 =16

Answer:

y = (1/4)x - 3

Step-by-step explanation:

The slope-intercept form is y = mx + b.  Here we are told that the line passes through (-8, -5) and that its slope is 1/4 (is that correct?).  

Substituting -5 for y, -8 for x and 1/4 for m, we get an equation for the y-intercept, b:

-5 = (1/4)(-8) + b, or

-5 = -2 + b, so b = -3, and the desired equation is

y = (1/4)x - 3

What is If a rectangular prism has a length, width, and height of centimeter, centimeter, and centimeter, respectively, then the
USPshnik [31]

Answer:

The volume is 105/512 cubic inches

Step-by-step explanation:

Given [Missing from the question]

L = \frac{3}{8} cm -- Length

W=\frac{5}{8}cm -- Width

H = \frac{7}{8}cm -- Height

Required

Determine the volume.

The volume (V) is calculated as thus:

V = L *W *H

V = \frac{3}{8} cm* \frac{5}{8}cm * \frac{7}{8}cm

V = \frac{3}{8} * \frac{5}{8} * \frac{7}{8}cm^3

V = \frac{3*5*7}{8*8*8}cm^3

V = \frac{105}{512}cm^3
