Answer:

Step-by-step explanation:

First, we need to find x. We are given the perimeter, which is 2l + 2w, so from there, we have an equation of 2(4x-1) + 2(3x+2) = 100. By working through it, we get that x = 7. We're asked to find WX, so plug 7 into 4x - 1 and get 27.

Answer:

<h3>27 <em>units</em></h3>

Step-by-step explanation:

Perimeter of rectangle is 2(l) + 2(w).

The perimeter is given 100 units.

2(4x-1) + 2(3x+2) = 100

Solve for x.

8x-2+6x+4=100

14x+2=100

14x=98

x=7

Plug x as 7 for the side <em>WX</em>.

4(7) - 1

28-1

= 27

What is the the answer to 6/12 x2/3

mr_godi [17]

To multiply two fractions together, multiply the numerators of both fractions together and same goes for the denominators.

$\frac{6}{12} * \frac{2}{3} = \frac{12}{36}$

Simplify.

$\frac{12}{36} = \frac{1}{3}$

So, 1/3 is the answer.
