Answer:
x=7
Step-by-step explanation:
5x%2B7=6x Start with the given equation.
5x=6x-7 Subtract 7 from both sides.
5x-6x=-7 Subtract 6x from both sides.
-x=-7 Combine like terms on the left side.
Divide both sides by -1 to isolate x.
x=7 Reduce.
Answer:
idk thats tough
Step-by-step explanation:
I personally would say neither because they either aren't the same or there not equivalent.
(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.
