Answer:

Option B

Option C

Option D

All of these are correct

Step-by-step explanation:

Option B is correct because:

2x + 1 + 2x + 3 = 4x + 4

=> 4x + 4 = 4x + 4

Option C is correct because:

x + 3x + 4 = 4x + 4

=> 4x + 4  = 4x + 4

Option D is correct because:

2(2x + 2) = 4x + 4

=> 4x + 4 = 4x + 4

Option A is incorrect because:

4(x + 4) = 4x + 4

=> 4x + 16 ≠ 4x + 4

Factor completely. -2k - k3^ - 3k^2
wlad13 [49]

Answer:

-k(k+1)(k+2)

Step-by-step explanation:

Begin to factor by using GCF by finding the greatest common factor. Here it is k.

-2k-k^3-3k^2 = -k(2+k^2+3k)

We will rearrange and factor the trinomial.

-k(2+k^2+3k)\\-k(k^2+3k+2)\\-k(k+1)(k+2)

Determine the functions value when x= -1?a. g(-1) = -3b. g(-1) = 0c. g(-1) = 1d. g(-1) = 27
Ber [7]

Problem

Determine the functions value when x= -1?

a. g(-1) = -3

b. g(-1) = 0

c. g(-1) = 1

d. g(-1) = 27​

Solution

For this case we just need to find the value of g when x= -1 and if we look at the table we got:

g(-1)= (-1)^3 + 6(-1)^2 +12(-1) +8

g(-1)= -1 +6 -12+8 = 5-12+8= 1

And then the solution for this case would be:

c. g(-1) = 1

The value of square root of 578

Also, the square of 24 is equal to 576.

Thus, Navigator is correct because both values are approximately equivalent.

<em>If the values are much less or more than the 576 then Navigator mist give the more precise answer.</em>
