Answer:
no
Step-by-step explanation:
12x-20x=-8x
so it would be -8x>-40
and you would divide both sides by -8
and get x<5
(7x + 4)(7x + 4) and (x – 9)(x – 9) are Perfect square trinomial. (5x + 3)(5x – 3) and (–3x – 6)(–3x + 6) shows the Difference of squares.
<h3>What is a perfect square?</h3>
A perfect square is a number system that can be expressed as the
square of a given number from the same system.
The following are the answers
(5x + 3)(5x – 3) Difference of squares
(7x + 4)(7x + 4) is a Perfect square trinomial
(2x + 1)(x + 2) has Neither a difference of squares nor a perfect square trinomial.
(4x – 6)(x + 8) has Neither a difference of squares nor a perfect square trinomial.
(x – 9)(x – 9) is Perfect square trinomial
(–3x – 6)(–3x + 6) = Difference of squares.

Answer:
1 1/2 kg de queso
Step-by-step explanation:
De la pregunta anterior, sabemos que:
1 queso = 1/4 kg
6 quesos = x kg
Multiplicar cruzada
1 queso × x kg = 6 quesos × 1/4 kg
x kg = 6 quesos × 1/4 kg / 1 queso
x kg = 3/2 kg
x kg = 1 1/2 kg de queso
