QR = 23
Because the triangles are equal to each other, sides QR and TV are also equal. You can create an 3 or 4 step equation by writing the the QR equation is equal to the TV equation and then solving for X. After you solve for X, plug it back into the QR equation to solve for QR.
The area of the rectangle is 64.8 square .inch
<h3>What is a Rectangle ?</h3>
A rectangle is a polygon with four sides , opposite sides are parallel and equal.
It is given that
A rectangle is divided into exactly 20 congruent squares
If they are lined up the Length is 36 inches
Therefore the length of each square or the side of the square = 36/20
= 1.8 inch
The area of the rectangle will be
20* Side of square * Side of square
=20*1.8*1.8
= 64.8 square inch
The area of the rectangle is 64.8 square .inch

Answer:
x = i sqrt(14/19) or x = -i sqrt(14/19)
Step-by-step explanation:
Solve for x:
(-38 x^2 - 28)/(x^2 - 5 x - 2) = 0
Multiply both sides by x^2 - 5 x - 2:
-38 x^2 - 28 = 0
Add 28 to both sides:
-38 x^2 = 28
Divide both sides by -38:
x^2 = -14/19
Take the square root of both sides:
Answer: x = i sqrt(14/19) or x = -i sqrt(14/19)
