5x7=35
5x7=5x(5+2)
5x7=(5x3)+(5x4)
5x7=20+15
5x7=35
This is how I would do it :)
The products that result in a perfect square trinomial is (x + y + x)(x + y + x), (2x - 3)(-3 + 2x) and (4y² + 25)(25 + 4y²)
<h3>What is an
polynomial?</h3>
A polynomial is an expression that involves only the operations of a<em>ddition, subtraction, multiplication</em> of variables.
A perfect square trinomial is the square of a binomial
(x + y + x)(x + y + x) = (2x + y)²
(2x - 3)(-3 + 2x) = (2x - 3)²
(4y² + 25)(25 + 4y²) = (4y² + 25)²
The products that result in a perfect square trinomial is (x + y + x)(x + y + x), (2x - 3)(-3 + 2x) and (4y² + 25)(25 + 4y²)

Answer:
<h2>x = 88.2</h2>
Step-by-step explanation:
Look at the picture.
Use tangent:

We have a measure of the angle and length of the adjacent:


Substitute:
<em>multiply both sides by 500</em>
