The answer is 100x2 because 20x5= 100 and the power of 2 is alone, so that’s the answer.

√20x *√5x3 - We can involve the action under the square root, because we have a multiplication of two square root elements.

$\sqrt{20x*5x^{3}} = \sqrt{20*5 x^{4} } = \sqrt{100} *x^{2} = 10x^{2}$

We are using the fact, that the multiplication of the square roots is alternating.

Answer:

x = 26

Step-by-step explanation:

it is a right angle so

(x+4)3=90

3x+12=90

-12 -12

3x = 90-12

3x = 78

/3 /3

x = 26

Answer:

Step-by-step explanation:

$\sqrt{2x+3} \sqrt{x-2} =\sqrt{(2x+3)(x-2)} =\sqrt{2x^2-4x+3x-6} =\sqrt{x^2-x-6}$

How do you do this question?

polet [3.4K]

Answer:

7

Step-by-step explanation:

1 / ((n + 1) + 2)³ ≤ 0.001

1 / (n + 3)³ ≤ 0.001

(n + 3)³ ≥ 1000

n + 3 ≥ 10

n ≥ 7

A line segment has (x1, y1) as one endpoint and (xm, ym) as its midpoint. Find the other endpoint (x2, y2) of the line segment i

Levart [38]

Answer: (a) ( $x_{2},y_{2}$ ) = (3,2)

(b) ( $x_{2},y_{2}$ ) = (19,-7)

Step-by-step explanation: Midpoint of a segment is halfway between 2 endpoints. It is calculated using the formulas:

$x_{m}=\frac{x_{1}+x_{2}}{2}$

$y_{m}=\frac{y_{1}+y_{2}}{2}$

Isolating $x_{2}$ :

$2x_{m}=x_{1}+x_{2}$

$x_{2}=2x_{m}-x_{1}$

And $y_{2}$ :

$2y_{m}=y_{1}+y_{2}$

$y_{2}=2y_{m}-y_{1}$

(a) Replacing values and calculating $x_{2}$ :

$x_{2}=(2*2)-1$

$x_{2}=3$

Calculating $y_{2}$ :

$y_{2}=[2*(-1)]-(-4)$

$y_{2}=2$

$(x_{2},y_{2})=(3,2)$

(b) $x_{2}=(2*5)-(-9)$

$x_{2}=19$

$y_{2}=(2*6)-19$

$y_{2}$ = -7

$(x_{2},y_{2})=(19,-7)$
