Using the distributive property, marta multiplied the binomial (2x + 3) by the trinomial (x2 + x - 2) and got the expression below.
(2x)(x? ) + (2x)(x) + () + (3)(x? ) + (3)(x) + ()
which is the simplified product?
2x3 + 6x2 - x - 6
2x3 + x2 - x - 6
2x3 + 5x2 – x-6
2x3 - x2 - 7x-6

how to award brainliest:

you must wait until 2 people answer to award brainliest. i'm pretty sure that it should be next to the "" and "comments" buttons.  

2 over 5 and 4 over 15

don’t know last one sorry

step-by-step explanation:

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
