We can factor by grouping like so

3v^2 + 16v + 5

3v^2 + 15v + v + 5

3v(v + 5) + 1(v + 5)

(3v+1)(v+5)

---------

Check:

(3v+1)(v+5)

w(v+5) ... let w = 3v+1

vw + 5w

v(w) + 5(w)

v(3v+1) + 5(3v+1) .... plug in w = 3v+1

3v^2+v + 15v + 5

3v^2 + 16v + 5

We get the original expression again, which confirms the answer.

Answer:

9%

Step-by-step explanation:

Let the required number be 100.

Now, according to the question, the number is first increased by 30 %

⇒ 100 + 30 % of 100

⇒ 100 + [(30*100)/100]

⇒ 100 + 30

⇒ 130

Then, it is decreased by 30 %

⇒ 130 - (30 % of 130)

⇒ 130 - [(30*130)/100]

⇒ 130 - 39

⇒ 91

Net Decrease = 100 - 91

= 9

Percent Decrease = (Change in number*100)/100

⇒ (9*100)/100

= 9 %

Which ordered pair makes both inequalities true?
Digiron [165]
For a
0 > -3(1) + 3 i.e. 0 > 0 (not true)
For b
1 > -3(-1) + 3 i.e. 1 > 6 (not true)
For c
2 > -3(2) + 3 i.e. 2 > -3 (true)
2 > 2(2) - 2 i.e. 2 > 2 (not true)
For d
3 > -3(0) + 3 i.e. 3 > 3 (not true)

Therefore, none of the ordered pairs makes both inequalities correct.
