ok ... so the way i solved this is by finding the correct side measurements ... so in this there are 2 rectangles ... so lets find the area of both rectangles individually and then add it together ... so the rectangle on the top will be <em><u>a</u></em><em> </em>and the down one will be <u><em>b </em></u>

rectangle a :

as we know ... a <u>rectangle has opposite sides equal . </u> the side on the right is 20 ... subtract it from 11 ... if we do that we get 9 ... which is the length of rectangle a and as the top is 7 bottom will be 7 too

now we know the sides of rectangle <u>a </u>which is 7 and 9

and area of rectangle : l × b , ∴ 7×9= 63

now b ... sides of rectangle b are 14 and 11

so 14×11= 154

now add it ... <u>154 + 63 = 217 </u>

∴ = 217 sq.

A = 7*9 +11*14
=63 + 154
=217 cm^2

Suppose j varies jointly with g and v, and j=1 when g=4 and v=5. what is j when g=10 and v=9?
Tems11 [23]
J\alpha gv
j=agv where a is a constant of proportionality.
j=1 when g=4 and v=5
1=a*4*5
1=20a
a=1/20
a= 0.05
j=0.05gv
When g=10 and v=9,
j=0.05*10*9
j=0.5*9
j=4.5

Find the difference of(ab+8a+1)-(-6ab+4)
vagabundo [1.1K]
Hey there!

When finding the difference of expressions like these, there's a few things you should keep in mind. 

1. When finding the difference of two polynomials, multiply the polynomial that implied to be "negative" by –1 to expand the problem and make it easier to solve. 

2. You combine terms based on their unknown terms, like x, y, x², ab, etc. You cannot combine the terms x and x², but you can combine the terms 6b and 8b by adding them. 

3. You can rearrange your terms however you see fit. If a polynomial is implied as "positive", you can multiply that entire polynomial by +1 to get rid of the parentheses. 

With all that in mind, you can go ahead and solve for your difference, like so:

(ab+8a+1)-(-6ab+4)

(ab+8a+1) (-1(-6ab+4))

(ab+8a+1) + (6ab-4)

ab+6ab+8a+1-4

7ab+8a-3

7ab+8a-3 will be your difference. 

Hope this helped you out! :-)

Compré 5 distintos tipos de semillas de flores para sembrarlas en el jardin una tras de otra.
Colt1911 [192]

Responder:

120 maneras.

Explicacion paso a paso:

Cinco tipos diferentes de semillas.

El numero de formas de organizar, n, a diferencia de los objetos en una linea es n!

Entonces, para sembrar 5 tipos diferentes de flores, serian 5!

5! = 5 * 4 * 3 * 2 * 1 = 120 vias.

Por lo tanto, hay 120 formas de sembrar las cinco semillas.

Hablo ingles y escribo ingles. Espero que entiendas. Acabo de utilizar el traductor de Google para intentar que la respuesta sea mas clara para ti :).

Por favor, califique con 5 estrellas, gracias, y deme lo mejor (Brainliest). Gracias.
