1. Perfect square trinomials, are 2nd degree polynomials, of the form

so that

, which can be written as perfect squares.
2. For example

3. Thus

are perfect square trinomials.
4.

5. In the first case -b=20, so b=-20. In the second case, -b=-20, so b=20.
6. b∈{-20, 20}
Answer:
5/12
Step-by-step explanation:
can't be anymore simplified, it already is
Answer:
2x+2y ≤ 64
x=2y+2
Step-by-step explanation:
x = length
y = width
the length is 2 more than twice the width or 2 more than twice y
x = 2+2y
the perimeter of the garden = 2 times the length + 2 times the width
she have 64ft of wire so the perimeter should be equal or less than 64 ft
64 ≥ 2x + 2y
