Find the product of (x − 5)2. (1 point) Group of answer choices x2 + 10x + 25 x2 − 10x + 25 x2 − 25 x2 + 25

Answer:

$x^2 - 10x + 25$

Step-by-step explanation:

Hello!

Expand the square using the Distributive Property.

<h3>Expand</h3>

$(x - 5)^2$
$(x - 5)(x-5)$

Distributive x - 5 to each factor

$x(x - 5) -5 (x - 5)$
$x^2 - 5x - 5x+25$
$x^2 - 10x + 25$

The answer is $x^2 - 10x + 25$ .

We can also use a special binomial product formula.

Formula: $(a - b)^2 = a^2 - 2ab + b^2$

$(x - 5)^2 = x^2 - 2(x)(5) + 5^2$
$(x - 5)^2 = x^2 - 10x + 25$

We get the same answer both ways.

I WILL MARK BRAINIEST <br> please answer question 5

Marat540 [252]

Answer:

a = 150

Step-by-step explanation:

The sum of the internal angles of an octagon is 1080°.

$4a+4(120)=1080$ (There are four $120^{\circ}$ and 4 $a^{\circ}$ , they sum to 1080°)

$4a + 480 = 1080$

$4a = 600$

$a = 150$

Hope this helps :)
