I need an explanation for the problem 4v2=-12v-9. I don't understand why it factors into 4v+3 and 4v+3
kirza4 [7]

Answer:

The factors are 2v+3,2v+3.

The factors are not 4v+3,4v+3

Step-by-step explanation:

Equation is 4v^2=-12v-9.

This equation can be written as follows:

4v^2+12v+9=0

Here,

12v=6v+6v

Therefore,

4v^2+6v+6v+9=0\\2v(2v+3)+3(2v+3)=0\\(2v+3)(2v+3)=0

So, the factors are 2v+3,2v+3.

The factors are not 4v+3,4v+3

How many integers n leave remainder 4 when divided by 7, if n satisfies the given inequality?
bekas [8.4K]

Consider inequality |-n| This inequality is equivalent to inequality |n|

This means that -46

The greatest integer number n, such that -46 when dividing by 7 gives the remainder 4 is 39. Then subtract 7, you get 32, then 25 and so on.

When n=-39, -32, -25, -18, -11, -4, 4, 11, 18, 25, 32, 39 then dividing by 7 the remainder is 4.

Answer: 12 integers.
