< and > is greatest and smallest and = is equal like 34 and 34 are equal and 34 and 35 r big and little
34 < 35.
34=34
86 > 45
Answer:
18-15
Step-by-step explanation:
Factoring a trinomial is a tedious process, sometimes involving a trial-and-error process. The best approach would be to try out all the choices, replace them with x, and see if it satisfies the equation to be equal to zero. Since no choice are given, we use another technique: by using the scientific calculator under mode EQN (equation).
Once you're in mode EQN, choose the trinomial (ax^3 + bx^2 +cx +d =0).Then, all you have to do is substitute the coefficients (a=3, b = 8, c = -87, d = 28). Press equals, then the three roots would appear.
The roots, and therefore factors, are -7, 4 and 1/3. Any of those are factors of the given equation.

With the properties of rectangle in mind we must perform two verification. Verify to see if opposite sides are parallel and adjacent sides are perpendicular.
We need to determine the slope of each side, using the formula,

<u>Slope of AB</u>




<u>Slope of BC</u>



<u>Slope of CD</u>




<u>Slope of AD</u>



<u>Verify Parallel sides</u>
If the quadrilateral is a rectangle, then opposite sides should have the same slope. But


<u>Verify Perpendicularity</u>
And also the product of slopes of all sides with a common vertex should be -1. But




Since the quadrilateral fails to satisfy all these conditions, the quadrilateral is not a rectangle
