Answer:

Factorized

$=(2x-8)(x-3)$

Roots : 4 , 3

Step-by-step explanation:

If it is to factorize :

$2x^2 - 14x + 24 = 2x^2 -6x-8x +24$

$=2x(x-3)-8(x-3)\\=(2x-8)(x-3)$

If it is to solve for x :

$2x^2 -1 4x + 24 = 0\\(2x-8)(x-3)=0\\2x - 8 = 0 \ , \ x - 3 = 0\\2x = 8 \ , \ x = 3\\x = 4 , 3$

prisoha [69]

Answer:

The length of the shortest side of the triangle is 10.

Step-by-step explanation:

Given that the lengths of the sides of a triangle are 4, 5 and 6, if the length of the longest side of a similar triangle is 15, to determine what is the length of the shortest side of the triangle, the following calculation must be performed :

6 = 15

4 = X

4 x 15/6 = X

10 = X

Therefore, the length of the shortest side of the triangle is 10.
