ANSWER

A.

{(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

Are You guys up for math?? Its 6th grade math though!! so are you ready?? l want help please.
katen-ka-za [31]

The ratio would be 4:1.

Try to reduce the ratio further with the greatest common factor (GCF).

The GCF of 64 and 16 is 16

Divide both terms by the GCF, 16:

64 ÷ 16 = 4

16 ÷ 16 = 1

The ratio 64 : 16 can be reduced to lowest terms by dividing both terms by the GCF = 16 :

64 : 16 = 4 : 1

Therefore:

64 : 16 = 4 : 1

The probability would be 6/16 or 37.5% because there are 16 coins in total and 6 of them are worth more than 5 cents. :)

Cole is studying employment trends.
natali 33 [55]

Answer:

225

Step-by-step explanation:

So we know that 20% of the social workers he surveyed was 45 people. The easiest way to find all 100% of the social workers is to do 45 x 5 because 20% x 5 = 100%. So 45 x 5 = 225.

Hope this helped! :)

Alchen [17]

Answer:

d = 2/27

Remember that when a variable is times with a number you <u>divide</u> the number on both sides.

When a variable is divided by a number, you <u>multiply</u> the number on both sides.

Hope this helps you and thank you !!

What is the y and x intercept for f(x)=3x-2 find f(-5)​
masya89 [10]

Answer:  The y- intercept is -2.  The x-intercept is 2/3

The attachment shows the solutions.

Step-by-step explanation:  The y-intercept is the "b" term in the slope-intercept form of the equation. To find the x-intercept, substitute 0 for the output and solve for x.

0 = 3x -2 . Add 2 to both sides

2 = 3x . Divide both sides by 3

2/3 = x   the x-intercept is 2/3

To find f(-5) substitute -5 for x and solve.

f(-5) = 3(-5) -2

f(-5) = -15 -2

f(-5) = -17
