Answer: 
Step-by-step explanation:
<u>Given the system of equation</u>


<u>Expand the parenthesis of the 1) equation</u>




<u>Current System</u>


<u>Substitute the y value of the 1) equation with the 2) equation</u>

<u>Add ( x² + 4x + 3) on both sides</u>


<u>Combine like terms</u>


<u>Factorize the quadratic equation</u>


<u>Substitute the x values into one of the equations to find the y value</u>



<u>Therefore, the two solutions are:</u>

Answer:
16 units.
Step-by-step explanation:
Just to make things easy, let's name the points A(3,9) B(5,9) C(3, 3) and D(5, 3).
Because this question wants perimeter, we'll just use the distance formula twice, then l*2 + w*2 = p.
Distance formula is sqrt((x1 - x2)^2 + (y1 - y2)^2) = d.
sqrt((5 - 3)^2 + (9 - 9)^2) = 2
sqrt((5 - 5)^2 + (9 - 3)^2) = 6.
The distance of points A and B is 2 units, and B to D is 6 units, multiply both by 2, (2*2=4, 6*2=12) and add the values to find 16 units.
Hope this helps, and if this is for OW, I feel your pain.
