Given the arithmetic sequence an = 2 + 4(n − 1), what is the domain for n?

1 answer:

6 0

You first want to subtact 4n with n which would give you 3n. Then u would do
3n=2+ -4 Then you would add 4 and 2 which would give you 6. then u divide by 3 which would give u 2. N=2

The rectangles in the figure below are similar. Find the value of x

V125BC [204]

Answer:

C. 6

Step-by-step explanation:

It is given that the rectangles in the figure are similar.

<em>Thus, the corresponding sides of the two rectangles will be equal.</em>

So, we get,

$\frac{3}{x}=\frac{5}{x+4}$

i.e. $3(x+4)=5x$

i.e. $3x+12=5x$

i.e. $2x=12$

i.e. x = 6.

Hence, the value of x is 6.

A mirror is in the shape of an isosceles right triangle and has a hypotenuse length of seven times the square root of two. What

frez [133]

The length of one of the legs of an isosceles right triangle and has a hypotenuse length of seven times the square root of two is 7 units.

<h3>What is an Isosceles triangle?</h3>

Isosceles triangles are triangles that has two of it sides equal to each other. The base angles of an isosceles triangle are equal.

The isosceles triangle is also a right angle triangle. The hypotenuse is the longest side of a right angle triangle.

Therefore,

hypotenuse = 7(√2)

let the length of the other legs = x

Therefore, using Pythagoras theorem

c² = a² + b²

(7(√2))² = x² + x²

49 × 2 = 2x²

98 = 2x²

x² = 98 / 2

x = √49

x = 7 units

The length of a rectangle is 2 meters less than 3 times the width. The perimeter is 44

Yakvenalex [24]

Answer:

Width of rectangle = 6 meters

Step-by-step explanation:

Let

Width of rectangle = x

Length of rectangle = 3x-2

Perimeter of rectangle = 44 meters

We need to find:

The Width of rectangle.

The formula used is:

$Perimeter\:of\:rectangle=2(Length\times Width)$

Putting values and finding value of x

$Perimeter\:of\:rectangle=2(Length\times Width)\\44=2(3x-2+x)\\44=2(4x-2)\\44=8x-4\\8x=44+4\\8x=48\\x=\frac{48}{8}\\x=6$

So, we get the value of x = 6.

We know that Width of rectangle = x = 6

So, Width of rectangle = 6 meters
