Q # 15 I need help please to resolve

kow [346]

The sequence is

740, 707.60,675.20,642.80,...

Here first term is 740, and common difference, d is

$707.60-740 = -32.40$

Now we use the formula of nth term, which is

$a_{n} = a+(n-1)d$

Substituting the values of a,n and d, we will get

$=740+(n-1)(-32.40), 23 months$

Correct option is the second option .

Simplify this expression: (-2 - 8x) + (-4x - 10)

nevsk [136]

Answer:

The simplified form of expression (-2 - 8x) + (-4x - 10) is

-12(x + 1)

Step-by-step explanation:

It is given an expression (-2 - 8x) + (-4x - 10)

To find the simplified expression of (-2 - 8x) + (-4x - 10)

Let expression is given by

(-2 - 8x) + (-4x - 10) = -2 - 8x -4x -10

= -2 -10 -4x -8x

= -12 -12x

-12(x + 1) (since -12 is common in both terms)

Therefore simplified form is -12(x + 1)
