Answer:

\Large \boxed{\sf A}

Step-by-step explanation:

\displaystyle 2x\sqrt{44x}-2\sqrt{11x^3}

Let<em> x</em>  = 2 because x > 0

\displaystyle 2(2)\sqrt{44(2)}-2\sqrt{11(2)^3}=4\sqrt{22}

See which expression is equal to 4√22 when <em>x</em> = 2

2(2)\sqrt{11(2)}=4\sqrt{22}

The expression is option A

horrorfan [7]
The slope:
m = ( y2 - y1 ) / ( x2 - x1 ) = ( 8  2 ) / ( 3 - 2 ) = 6 / 1 
m = 6  ( we have the same slope for AB and A`B` )
AB = √[( 3 - 2 )² + ( 8 - 2 )²] = √37
A`B` = 3.5 √37 = 21.29

help please! the pair of figures to the right are similar. what is the ratio of the perimeters and the ratio of the areas?
jasenka [17]

Answer:

Perimeters = 3 in : 7 in

Areas = 9 in² : 49 in²

Step-by-step explanation:

    <em>If the figures are </em><em>squares</em><em>, and the measurements are the length of that sides (as you have said), then we will do the following. </em>

[The left square]

P = 4a

P = 4(15)

P = 60 in

-

A = a²

A = 15²

A = 225 in²

[The right square]

P = 4a

P = 4(35)

P = 140 in

-

A = a²

A = (35)²

A = 1,225 in²

[Simplifying ratios]

Perimeters = 60 in : 140 in

Perimeters = 6 in : 14 in

Perimeters = 3 in : 7 in

-

Areas = 225 in² : 1,225 in²

Areas = 45 in² : 245 in²

Areas = 9 in² : 49 in²

Please any one help me​
ivolga24 [154]

Answer:

k=30

Step-by-step explanation:

The formula for calculating the mean from a frequency table is:

\displaystyle  \overline{x} =  \frac{ \sum \: fx}{ \sum f}

we have

  • \sum f = 30
  • \sum f x= 120 + 3k
  • \overline{x} = 7

So our equation is

\displaystyle 7=  \frac{ 120 + 3k}{30}  \\  \implies \dfrac{120 + 3k}{30}  = 7

Solving the equation yields:

\implies 120 + 3k = 210 \\  \implies 3k = 90 \\  \implies \boxed{k = 30}
