Step-by-step explanation:
1. You can calculate the perimeter of a parallelogram as following:
Where a+b+c+d are the lenghts of the sides.
By definition the parallelogram has two pairs of parallel sides, therefore:
a=c and b=d
Then, you can calculate the perimeter as following:
2. Let's call the adjacent side 
, then the other side is 2x+3.
3. Substitute values and solve for x:
4. Then the lenghts of the sides are:
Answer:
m<3
Step-by-step explanation:
Hello :
<span>Y=x²-2x-19 ...(1)
y+4x=5.....(2)
by (2) : y = 5-4x ....(*)
subsct in (1) : 5-4x</span>=x²-2x-19
x²+2x-24 =0
<span>Δ = 2²-4(1)(-24) = 100=10²
x1 = (-2-10)/2 =-6
x2= (-2+10)/2=4
if : x =-6 by(*) : y= 5-4(-6)=29
if x= 4 y = 5-4(4)=-11
</span><span>solution set system of equation is (-6,29) and (4,-11)______.</span>
