Brayden is simplifying the expression 4n – (n – 3)2. he begins by distributing the negative to the terms inside the parentheses. what should he have done instead?

Square the binomial.

Step-by-step explanation:

1. The form indicates that he must square the binomial.

2. By definition, the square of a binomial produces a trinomial, which has the following form:

3. Then, you have:

4. Therefore, the answer is the second option.

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
