Keisha says each of the following expression is actually a binomial in disguise: 1. 5x^2 + 8x + 7x^ 2 - 4x
2. (4x^3 - 9+ 3x) - (-7x^3 +3x +2)
3. 8x^2- 4x+4

Is she right about each expression and explain why.

step-by-step explanation:

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
