Laura has a backyard that she wants to renovate. Her

miskamm [114]

Answer:

Area of the walkway = 8x + 24

Step-by-step explanation:

Area of the total backyard = $l\times b$

Area of total backyard = $(x+6)\times (x+4) = x^{2} +10x + 24$

Now, Area of the rectangular garden = $l\times b$

Area of the rectangular garden = $x (x+2) = x^{2} + 2x$

Now area of the walkway poured with concrete = Area of the backyard - Area of the rectangular garden

= $(x^{2} +10x +24) - (x^{2} +2x)$

= $x^{2} + 10x +24 - x^{2} -2x$

= 8x + 24

The formula for the volume of a tetrahedron is given as v=sh. Rewrite the

IrinaK [193]

Answer:

h = 6 units

Step-by-step explanation:

The formula for the volume of a tetrahedron is given as :

V = sh

Where

s is area of base and h is height

Put s = 8 and V = 48 to find h as follows :

$h=\dfrac{V}{s}\\\\=\dfrac{48}{8}\\\\h=6$

So, the height of the tetrahedron is 6 units.

How do i factor the coefficent out of a variable, such as 2.4n+9.6 and -6z+12

ANEK [815]

You are factoring one or more linear expressions (but are not factoring variables).

2.4n+9.6 can be divided by 2.4 and then the result mult. by 2.4:

2.4n+9.6 = 2.4 [ n + 4 ]

Also: -6z+12= 6 [ -z + 2 ] Here I have simplified linear functions but factoring out common constant coefficients (not variables).

Please help!!!!! Key features of Graphs

krok68 [10]

The graph is **increasing on the interval (-2, 1)**because the graph has a positive slope from x=-2 to x=1. It’s **decreasing at the intervals (-infinity, -2) and (1, infinity)**because the graph has a negative slope between the x values -infinity to -2 and is also decreasing between the x values of 1 and infinity.

An 8-foot roll of wrapping paper costs $12.48. What is the price per inch?

Kisachek [45]

The price of this wrapping paper per inch is equal to $1,198.08.

Given the following data:

Cost of wrapping paper = $12.48.

Length of wrapping paper = 8 foot.

To determine the price of this wrapping paper per inch:

<h3>How to solve the problem.</h3>

In this exercise, you're required to solve for the cost of an 8-foot roll of wrapping paper that costs $12.48. Thus, we would convert the length of this wrapping paper in foot to inch and then multiply by $12.48.

Conversion:

1 foot = 12 inch

8 foot = X inch

Cross-multiplying, we have:

$X = 8 \times 12$

X = 96 inch

For price per inch:

$Price = 12.48 \times 96$

Price = $1,198.08
