A rectangle is 3 times as long as it is wide. if the area is 27 square feet, find its perimeter.

Marat540 [252]

W - a width
3w - a length
27 ft² - an area

Therefore:

w · 3w = 27
3w² = 27 |:3
w² = 9 → w = √9 → w = 3

3w = 3 · 3 = 9

width = 3
length = 9

The perimeter:

P = 2 · width + 2 · length

P = 2 · 3 + 2 · 9 = 6 + 18 = 24 ft.

Find the complete factorization of the expression. 12xy + 28xz A) 4yz(10x) B) 4yz(3x + 7x) C) 4x(3y + 7z) D) 4(3xy + 7yz)

VashaNatasha [74]

Answer:

<em>The correct option is: C) 4x(3y + 7z)</em>

Step-by-step explanation:

Given expression is: $12xy+28xz$

First we need to find the GCF(Greatest common factor) of $12xy$ and $28xz$ and then we will factor out that GCF.

$12xy \Rightarrow 2\times 2\times 3\times x\times y\\ \\ 28xz\Rightarrow 2\times 2\times 7\times x\times z$

We can see that the common factors are: $2,2, x$

So, the GCF will be: $2\times 2\times x= 4x$

Now factoring out $4x$ from the given expression, we will get.....

$12xy+28xz\\ \\ = 4x(\frac{12xy}{4x}+ \frac{28xz}{4x}) \\ \\ =4x(3y+7z)$

So, the complete factorization will be: $4x(3y+7z)$

What is the slope of the line passing through the points (2, 5) and (-1, -4)? show your work

Sati [7]

Answer:

We can solve this question using the slope equation which is y2-y1/x2-x1

If you use that formula and sub in the coordinates

-4 - 5 / -1-2

-9/-3

= 3

The slope should be 3/1
