5+(x-5)=x

Simplify the left side by combining like terms:

5 + x - 5 = x

5-5 = 0

x = x

X = All real numbers.

Answer:

1/60 probabiliity

Step-by-step explanation:

You have two independent events that you want to put together.

Let Pr. mean "probability"

Pr(5 from 10 cards and 2 on a dice ) = Pr(5 from 10 cards) * Pr( 2 on a dice)

Pr(5 from 10 cards and 2 on a dice ) =(1/10) * (1/6)

= 1/60

Pr(5 from 10 cards and 2 on a dice ) =0.0167

or 1.67% probability

There are two similar packages. The ratio of the volumes is 8:125. Determine the dimensions of the bigger package. The dimension

GREYUIT [131]

Step-by-step explanation:

since packages are similarsimilar packages. The ratio of the volumes is 8:125. Determine the dimensions of the bigger package. The dimensions of the smaller package are... Height= 45cm, Length= 80cm, and Width= 25cm.

Length of bigger package = 80×125/8=1250cm

Width of bigger package =25×125/8=390.625cm

Height of bigger package =45×125/8=703.125cm

Given that k(x) = (2x + 4)2

taurus [48]

Answer:

$f(x)=4x\\g(x)=x+2$

Step-by-step explanation:

Because we have to rewrite this equation in the format $f(g(x))$ , we have to divide, or factor to find basic terms,

Expanding the value of k(x), we have $k(x)=4x+8$ . We see that each term can be divisible by 4, so we can factor out 4 to get

$k(x)=4(x+2)$

Now, we have two different terms getting multiplied. We can separate the two to get $4 \text{ and} (x+2)$

Because we are multiplying 4 by the other term, this is represented by $4x$

Now, we can just set f(x) and g(x) to these functions:

$f(x)=4x\\g(x)=x+2$

Now, just to make sure, we can plug a value into k(x) and the same value into f(g(x)). Plugging in 1, we have (2(1)+4)2 as 2(2+4), which is 2(6) = 12.

Plugging 1 into f(g(x)), we can evaluate g(1) first, to get 1 + 2 = 3. Now, f(3) = 4(3)= 12, which is the same for k(x).
