Factor the expression. x2 – 2x + 1 A. (x – 1)2 B. (x + 1)2 C. (x + 1)(x – 1)

Naddika [18.5K]

ANSWER

${(x - 1)}^{2}$

EXPLANATION

The given expression is

${x}^{2} - 2x + 1$

We split the middle term to obtain,

${x}^{2} - x - x + 1$

Factor to obtain

$x(x - 1) - 1(x - 1)$

Factor further to get,

$(x - 1)(x - 1)$

This is the same as;

${(x - 1)}^{2}$

The correct choice is A

If a vector's magnitude is 36 units right and 33 units up, what's the approximate magnitude of a vector that's one-third the len

omeli [17]

Answer:

The correct option is B. 16.3

Step-by-step explanation:

We are given a vector with components

V = 36x +33y

To solve this problem, we find its magnitude

|V| = SQRT (36^2 + 33^2)

|V| = SQRT (2385)

|V| = 48.836

To find the magnitude of the new vector we divide by three the previous quantity

|V2| = 48.836/3 = 16.278
