<h2>Hey there </h2>

<h2>Answer:</h2>

<h3>- 1976</h3>

<h2>Step-by-step explanation:</h2>

{5x}^{2}  - 5x - 169 =  {2x}^{2}  + x + 5 \\  \\  {5x}^{2}  - 5x - 169 -  {2x}^{2}  - x + 5 = 0 \\  \\  {3x}^{2}  - 4x - 164 = 0

<h2>Therefore, finding the discriminant:</h2>

<h3>a = 3 b = -4 c = 164</h3>

<h3>We, know that to find discriminant. </h3>

<h3>b^2 - 4.a.c</h3>

<h3>(-4)^2-4.3.164</h3>

<h3>-8 - 1968</h3>

<h3>- 1976</h3>

<h2>Hope it help you</h2>

A rectangle has an area of 12 square feet and a length of 5 feet.What is its width?
MrMuchimi

Answer:

width = 2.4

Step-by-step explanation:

so we know that the formula to get an area of a square/rectangle is A=lw, where <em>A </em>is the<em> </em><em>area</em><em>, </em><em>l</em><em>  </em>is the<em> </em><em>length</em><em>, </em>and <em>w</em> is the <em>width</em><em>.</em>

we already have the area and the length, so all we need now is the width.

to find the width, simply plug in the area and the length into the formula, which will give you:

A = lw <em>-given formula</em>

12 = 5(w) <em>-plug in known variables</em>

12/5 = 5w/5 <em>-divide both sides by 5 to get x by itself</em>

2.4 = w <em>-turn the fraction into decimal if you prefer it that way</em>

<em>possible answers: </em><u><em>w = 2.4</em></u>, <em><u>w = 12/5</u></em>, or <u><em>w = 2 2/5</em></u>

after 3 minutes = 59

soup cools down 0.2c in 1 seconds
