Answer:

1/5 = 20%

20.000.000 x 20% =4.000.000 / year

from 2008 to 2010 is : 2 years

So the population in 2010 is : 20.000.000 + ( 4.000.000 x 2 ) = 28.000.000 population

$\frac{x {}^{ - 1}y {}^{ - 2} }{z {}^{ - 3} }$

if the upper number got power of negative it will go down and the down will go up

So that,

$\frac{z {}^{3} }{x {}^{1} {y}^{2} }$

Someone help me please. I don't just want the answer, I need an explanation on how it's done too.

NARA [144]

Answer:

Below.

Step-by-step explanation:

f) (a + b)^3 - 4(a + b)^2

The (a+ b)^2 can be taken out to give:

= (a + b)^2(a + b - 4)

= (a + b)(a + b)(a + b - 4).

g) 3x(x - y) - 6(-x + y)

= 3x( x - y) + 6(x - y)

= (3x + 6)(x - y)

= 3(x + 2)(x - y).

h) (6a - 5b)(c - d) + (3a + 4b)(d - c)

= (6a - 5b)(c - d) + (-3a - 4b)(c - d)

= -(c - d)(6a - 5b)(3a + 4b).

i) -3d(-9a - 2b) + 2c (9a + 2b)

= 3d(9a + 2b) + 2c (9a + 2b)

= 3d(9a + 2b) + 2c (9a + 2b).

= (3d + 2c)(9a + 2b).

j) a^2b^3(2a + 1) - 6ab^2(-1 - 2a)

= a^2b^3(2a + 1) + 6ab^2(2a + 1)

= (2a + 1)( a^2b^3 + 6ab^2)

The GCF of a^2b^3 and 6ab^2 is ab^2, so we have:

(2a + 1)ab^2(ab + 6)

= ab^2(ab + 6)(2a + 1).

Miguel bought 8 equally priced pens for $3.84.

11111nata11111 [884]

Answer:

For 15 pens, the cost is $7.2

Step-by-step explanation:

We know that:

8 pens = $3.84

Work:

8 pens = $3.84

Divide the RHS:

=> 1 pen = 3.84/8
=> 1 pen = 0.48

Multiply the RHS:

=> 15 pens = 0.48 x 1
=> 15 pens = $7.2

Hence, for 15 pens, the cost is $7.2

Hoped this helped.
