What is the answer to this -2x-4>10

bearhunter [10]

-2x - 4 > 10

Multiply both sides by -1 and reverse the inequality symbol.

2x + 4 < -10

Now subtract both sides by 4.

2x + 4 - 4 < -10 - 4

2x < -14

Divide both sides by 2.

2x/2 < -14/2

x < -7

Is the following sequence arithmetic? If so, what is the common difference?

Vsevolod [243]

Given:

The sequence is

1, 2, 4, 8, 16, ...

To find:

Whether the given sequence is arithmetic or not. If yes, then find the common difference.

Solution:

We have,

1, 2, 4, 8, 16, ...

Difference between consecutive terms are

$d_1=a_2-a_1$

$d_1=2-1$

$d_1=1$

Similarly,

$d_2=a_3-a_2$

$d_2=4-2$

$d_2=2$

Since, $d_1\neq d_2$ , therefore the given sequence have no common difference between consecutive terms.

So, the given sequence is not arithmetic.

Therefore, the correct option is c.

Answer:

C. $(4x-8)^2$

Step-by-step explanation:

We need to determine whether the given polynomial $16x^2-64x+64$ can be factored into perfect squares. If so, factor the polynomial. Otherwise, select that it cannot be factored into a perfect square.
