Determine the value of c that will result in a perfect square trinomial. <br> w^2+6w+ c =130+c
Genrish500 [490]

Answer:

The value of c that will result in a perfect square trinomial is (3)^2 or 9

The perfect square trinomial is: (w+3)^2=139

Step-by-step explanation:

We need to determine the value  of c that will result in a perfect square trinomial.

w^2+6w+ c =130+c

Perfect square trinomial are of form: a^2+2ab+b^2=(a+b)^2

Now, the equation given is:

w^2+6w+ c =130+c

Looking at the term 6w, we can write it as 2(w)(3)

We are given: a = w, 2ab = 2(w)(3) so, b will be: (3)^2

So, we will be adding (3)^2 on both sides

w^2+6w+ c=130+c\\w^2+2(w)(3)+ (3)^2 =130+(3)^2\\The\:left\:side\:becomes: a^2+2ab+b^2\\We\:can\:write\:it\:as: (a+b)^2\\We\:have\:a=w\: and\: b=3\\(w+3)^2=130+9\\(w+3)^2=139

So, The value of c that will result in a perfect square trinomial is (3)^2 or 9

The perfect square trinomial is: (w+3)^2=139

A carpenter cut a board 334 feet long to make a shelf. Before he cut the board, it was 1012 feet long.
KiRa [710]
678 is what you have left but if you would put it as a fraction  of what you have left now it would be 678/1012... which then take and put it as a decimal which is a form of a mixed number = .6699

What set of three numbers could represent the lengths of the side of a right triangle?
klemol [59]

Answer:

C.) 5, 12, 13

Step-by-step explanation:

In a right triangle, the sum of the squares of the two shorter sides must equal the square of the longest side (Pythagoras).

a² + b² = c²

We can test each set of numbers to see which one fits.

A.) 8² +  12² =   16²

    64 + 144 = 256

           208 ≠ 256

B.) 6² +  7² =  8²

   36 + 49 = 64

           85 ≠ 64

C.) 5² +  12² =   13²

    25 + 144 = 169

            169 = 169

The numbers 5, 12, and 13 could represent the lengths of the sides of a right triangle.

D.) 16² +    32² =    36²

   256 + 1024 = 1296

              1280 ≠ 1296
