V / -0.8 +14=39 plssss help this is literally so hard ​
Nat2105 [25]
<h2><u>Answer:</u></h2><h2> \boxed{\boxed{\sf~v=-20}}</h2><h2 /><h2><u>Solution Steps:</u></h2>

______________________________

<h3>1.) Subtract 14 from both sides:</h3>
  • 14-14= Cancels Out
  • 39-14=25

<em>  - We do this because we have to get 2 variables/numbers on each side of the equals, and the only way to do so is to cancels other numbers out by doing the opposite of what we see. </em>

<u>Equation at the end of Step 1: </u>

  • v ÷ -0.8=25

<h3>2.) Multiply both sides by −0.8:</h3>
  • -0.8 × -0.8= Cancels Out
  • 25 × -0.8=-20

What are the extremes of the following proportion? 3⁄15 = 12⁄60
pashok25 [27]

<u>Answer:</u>

3 and 60

<u>Step-by-step explanation:</u>

For the given proportions, \frac { 3 } { 15 } = \frac { 12 } { 60 }, 3 and 60 are the extremes while 12 and 15 are the means.

To understand this, we can take a look at an example.

Suppose two ratios a:b and c:d are in proportion.Then it can be expressed as :

ab=cd

Here, a and d are the extreme ends and b and c are the means.

Zeros: x=1 (multiplicity 2) and x=-4
BARSIC [14]
Starting with x=1, subtract 1 from each side,
(x-1)=0

Our polynomial will have multiplicity of 2 for this particular zero,
(x-1)(x-1)

and do similar with the x=-4, add 4 to each side,
(x+4)=0

So our final result is: (x-1)(x-1)(x+4)

Expand out the brackets if you need this in standard form.
