Which of the following polynomials has zeros at x = –4 and x = 7?
4x 2 - 7x - 11

4x 2 - 49

7x 2 - 4x + 28

x 2 - 3x - 28

The correct option is 4.

Explanation:

It is given that the polynomial has two zeros at x=-4 and x=7.

If a polynomial has zeros at x=c then (x-c) is a factor of the polynomial.

Since the polynomial has two zeros at x=-4 and x=7, therefore the polynomial has factor (x+4) and (x-7).

This equation is represented by option 4, therefore the option 4 is correct and the equation has zeros at x = –4 and x = 7.

based on context clues you gave i'm assuming the answer would be c.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
