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 $4v+3,4v+3$

Orders for a computer are summarized by the optional features that are requested. The proportion of orders with no optional feat

Scorpion4ik [409]

Answer:

(a) 71.00%

(b) 63.00%

Step-by-step explanation:

No optional features = 0.29

One feature = 0.34

Two features = 0.37

(a) The probability that an order requests at least one optional feature is 100% minus the probability of an order requesting no optional features:

$P=1-0.29=0.71=71.00\%$

(b) The probability that an order does not request more than one optional feature is 100% minus the probability of an order requesting two optional features:

$P = 1 -0.37=0.63 = 63.00\%$
