What binomial is a factor of the trinomial x^2-5x+4

Svetradugi [14.3K]

Explanation:

Let the equation be

⋅

. To factorize multiplication of a and c i.e. ac so that sum of factors, if ac is positive (and difference if ac is negative) is equal to b. Now split b into these two components and factorization will be easy.

Answer:

Step-by-step explanation:

Two similar polygons, means a similarity would exist in both polygons

Perimeter of a rectangle = 2(l +w)
Perimeter of the larger rectangle = 36 (because it's the largest figure)
equation becomes 36 = 2(L + W)
since L = 14, it becomes = 36 = 2(14 +W)
36 = 28 + 2W
2W = 36 - 28 = 2w = 8

w = 4.

Now we assume that since the rectangles are similar, they would have similar dimensions, in this case Width. so with this, we find length of smaller rectangle.

21 = 2(L + 4) = 21 = 2L + 8

2L = 21 - 8 = 2L = 13

L = 13/2 = 6.5.

lastly the product of the length of both polygons = 14 * 6.5 = 91.

Their Products length is 91
