Answer:
4
Step-by-step explanation:
with a 30-60-90 triangle the hypotenuse is 2x while the smaller 30 side is x. This means that LJ is 4
. Then for a 45-45-90 the hypotenuse is
compared to a leg being X. So you remove the
leaving you with 4
The perimeter of quadrilateral B is 12.
<u><em>Explanation</em></u>
Quadrilateral A has side lengths as 6, 9, 9 and 12. In quadrilateral B, length of the shortest side is 2.
As quadrilateral B is a scaled copy of quadrilateral A, so <u>the scale factor</u> will be...
<em>(Shortest side of B / Shortest side of A)</em> 
Now the remaining side lengths for quadrilateral B will be.....
and 
⇒ 3 , 3 and 4
Thus, the perimeter of quadrilateral B is

Answer:
The given table represents a function f(x) = y = 2x+3
The upper graph
Step-by-step explanation:
We will write the equation of the right line in the explicit (slope) form
y = ax+b
We will take two points from the given table
A(-1,1) and B(0,3) and insert their coordinates in the equation y=ax+b and get
A(-1,1) => 1 = (-1)*a+b => -a+b=1
B(0,3) => 3=0*a+b => 3= 0+b => b=3
Now we will insert b=3 in the equation -a+b=1 and get
-a+3=1 => a=3-1 => a=2
Now we will insert a=2 and b=3 in the equation y=ax+b and get
equation of the function
y = 2x+3 = f(x) The upper graph.
Good luck!!!
