A) ΔAED ~ ΔACB
B) ΔAED ≅ ΔACB
C) The area of ΔAED is half the area of ΔACB
D) The perimeter of ΔAED is one-fourth the area of ΔACB
-x + 6y = 26
Elimination
B=(xy + x)(xy + x)
C=(2x – 3)(–3 + 2x)
D=(16 – x2)(x2 – 16)
E=(4y2 + 25)(25 + 4y2)
The correct answers are:
B=(xy + x)(xy + x) ; C=(2x – 3)(–3 + 2x) ; and E=(4y² + 25)(25 + 4y²)
Explanation:
In order to have a perfect square trinomial, we must multiply two binomials that are exactly the same. For (xy+x)(xy+x), are multiplying two identical binomials.
For (2x-3)(-3+2x), we are multiplying two binomials that are the same but written in a different order. The same is true of (4y² + 25)(25 + 4y²).
Answer:
A and E and C
Step-by-step explanation:
A perfect square trinomial can be written as the square of a binomial.
