Select the correct answer.
simplify the expression (4x - 3)(x + 5).

Use FOIL to multiply binomials by multiplying each term in the first binomial by the terms in the second binomial.

(4x - 3)(x + 5)

4x^2+20x-3x-15

Now combine like terms.

answer : 4x^2+17x-15

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
