If the difference between two numbers is 7 and their product is 137 what is the sum of squares of the numbers

Mathematics

Answer:

x-y = 7 …(1)

xy = 137 …(2)

Square (1) to get x^2 +y^2 - 2xy = 49, or

x^2 +y^2 = 2xy + 49 = 2*137 + 49 = 323 + 49 = 372.

The sum of the squares of the two numbers is 372.

The square of the sum of the two number: (x+y)^2 = x^2+2xy+y^2 = x^2 +y^2 - 2xy + 4 xy = 49 +4*137 = 49+548 = 597.

C. Because you have to look for the greatest number. Disregard whether it is negative or positive. Since you are looking for steepness. That does not matter.

The area of a regular octagon is 35 cm 2 what is the area of a regular octagon with sides three times as large
Maurinko [17]
The area of a polygon = n*side^2 / (4 * tan(180/n))
where "n" is the number of sides

Let's calculate area for side = 2
area = 8*2^2 / (4 * tan(180/8))
area = 32 / (4 * tan(22.5))
area = 32 / 4*0.41421
<span> <span> <span> area = 19.3138746047 </span> </span> </span>

Now, let's calculate area for side = 6
area = 8*6^2 / (4 * tan(180/8))
area = 288 / <span> <span> <span> 1.65684 </span> </span> </span>
area = <span> <span> <span> 173.824871442 </span> </span> </span>

<span> <span> 173.824871442 </span> / </span><span><span>19.3138746047 = </span> 9

So, the area would be 9 times larger.

ALSO, looking at the formula
</span>n*side^2 / (4 * tan(180/n))
we can see that the side length appears just once in the formula and we are to square it in the calculation.  So, if we increase the side length is increased by 3, then the area increases by 3^2 or 9.
