The perimeter is 2(length) + 2(width), so 2(x+5) + 2(x+4) = 42 m. In solving for x, you find 6. Plug 6 back into your length and width where x originally was, and you find your length to be 11m, and your width to be 10m. Hope this helps!

Eliminate the parameter.<br><br><br>x = 5t, y = t + 8 (2 points)

Answer: y = $\frac{1}{5}$ x + 8

Step-by-step explanation:

This is asking us to remove the parameter. In other words, we want an equation with only the relation between x and y, so we need to remove the t. There are a few ways to do this, but I am going to set one equation equal to t and then plug it into the next one.

Given:

x = 5t

Divide both sides of the equation by 5:

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

Given:

y = t + 8

Plug in:

y = ( $\frac{1}{5}$ x) + 8

Answer:

y = $\frac{1}{5}$ x + 8
