Answer:
△PQR and △RST are not similar.
Step-by-step explanation:
In triangle △PQR, two known interior angles are 34° and 80°. So the measure of third angle is

In triangle △RST, two known interior angles are 24° and 90°.

Two triangles are similar if their corresponding angles are same and the corresponding sides are proportional.
Since the angles of △PQR and △RST are not same, therefore we can say that the △PQR and △RST are not similar.
In the matrix, the first row is exactly twice the second. This implies that the determinant is zero.
If the matrix system has determinant zero, the system has either no solutions or infinite solutions.
However, just like in the matrix, in the constant vector the first term is twice the second. This means that the system has infinite solutions.
In fact, if you write this system in expanded form, you can see that it generates two equations, the first being twice the second:

Answer:
f=
x2−2x+1
x3+2x2+x
Step-by-step explanation:
Let's solve for f.
fx=
(1−x)2
(1+x)2
Step 1: Multiply both sides by x^2+2x+1.
fx3+2fx2+fx=x2−2x+1
Step 2: Factor out variable f.
f(x3+2x2+x)=x2−2x+1
Step 3: Divide both sides by x^3+2x^2+x.
f(x3+2x2+x)
x3+2x2+x
=
x2−2x+1
x3+2x2+x
f=
x2−2x+1
x3+2x2+x
