The answer is triangular prism.

Step-by-step explanation:

Triangular prism has exactly three rectangular faces.

<u>Triangular Prism:</u>

Triangular prisms are three-dimensional solids formed by putting rectangles and triangles together. It is a polyhedron made of a triangular base, a translated copy, and 3 faces joining corresponding sides. A right triangular prism has rectangular sides, otherwise it is oblique.It is a three dimensional shape with two parallel congruent circular faces whose cross sections (taken parallel to these circular faces) are circular....

Write an recursive formula for an, the nth term of the sequence 19,22,25, ....

ra1l [238]

Answer:

$T_n = T_{n-1}+3$ where n>1

Step-by-step explanation:

Given

$19,22,25, ..$

Required

Determine the recursive formula

The given sequence shows arithmetic progression (AP).

First, we calculate the common difference (d):

$d = 22 - 19 = 25 - 22$

$d = 3$

The recursive formula of an AP is determined using:

$T_n = T_{n-1}+d$ where $n>1$

Substitute 3 for d

$T_n = T_{n-1}+3$ where $n>1$

The length of a rectangle is x feet. Its width is (x-7) feet. Draw and label a rectangle to represent this situation. Then write

a_sh-v [17]

Answer:

Perimeter of rectangle:

$(4x - 14)\text{ feet}$

Step-by-step explanation:

We are given the following in the question:

Length of rectangle:

$x\text{ feet}$

Width of rectangle:

$(x-7)\text{ feet}$

Perimeter of rectangle:

$2\times \text{(Length + Width)}$

Expressions to calculate perimeter

$1. ~2((x) + (x - 7))\text{ feet}\\2.~2(2x-7)\text{ feet}\\3.~ 4x-14\text{ feet}$

The attached image shows the image of the rectangle.
