Let x = the number

Let c = the factor

You want

√(cx) = 2√x

Solve for c:

cx = 4x

c = 4

You need to multiply by 4 to double the square root. Have a great day!!

2x - 5 < 33 what are all the values to this inequality

Lynna [10]

Answer:

x < 19

Step-by-step explanation:

Given that,

An inequality 2x - 5 < 33.

LHS of the inequality is 2x - 5

RHS of the inequality is 33

LHS < RHS

i.e.

2x - 5 < 33

Add 5 to both sides of the inequality

2x - 5 +5 < 33+5

2x < 38

Divide both sides by 2.

x < 19

So, the value of x is less than 19.

The area of rectangular kitchen tile is 6x^2-8x-30. The width is 2x-6.

mrs_skeptik [129]

Answer:

L=6x^2-4x+5

P=12x^2-4x-2

Step-by-step explanation:

A=WL

So, we know the area is 6x^2-8x-30 and the width is 2x-6

Substitute

(6x^2-8x-30)=(2x-6)(L)

L=(6x^2-8x-30)/(2x-6

Divide

L=6x^2-4x+5

P=2L+2W

Substitute

P=2(6x^2-4x+5)+2(2x-6)

P=12×^2-8x+10+4x-12

Simplify

P=12x^2-4x-2

If you know that the exact volume of a cylinder is 500 π cm3, how can you find the approximate volume, without knowing the heigh

allsm [11]

Answer:

The approximate volume is $1,570\ cm^{3}$

Step-by-step explanation:

we know that

The exact volume of the cylinder is

$V=500\pi \ cm^{3}$

To find the approximate volume of the cylinder, substitute the term $\pi$ by the approximate value of $3.14$ and then multiply

$V=500(3.14)=1,570\ cm^{3}$
