Audrey takes a sheet of paper and makes a diagonal cut from one corner to the opposite

Elodia [21]

$\large{\underline{\underline{\pmb{\frak {\color {blue}{Solution:}}}}}}$

Let us take the width of the paper as base, the cut she made be hypotenuse and the paper's length be perpendicular.

Here,

Hypotenuse (H) = 87 inch

Base (B) = 60 inch

Perpendicular (P) = [To be calculated]

As, we can use Pythagoras theorem to find. So by using Pythagoras theorem :

H² = P² + B²

${87}^{2} = {P}^{2} + {60}^{2} \\ \\ \implies \: 7569 = {P}^{2} + 3600 \\ \\ \implies \: 7569 - 3600 = {P}^{2} \\ \\ \implies3969 = {P}^{2} \\ \\ \implies \: P = \sqrt{3969} \\ \\ \implies \: P = 63$

The length of the paper is 63 inches.

Solve this using the quadratic formula. Show work<br><br> 2x^2+7x−5=0

kozerog [31]

Multiply the numbers (2*2=4)
$=\frac{-7+\sqrt{7^2-4\cdot \:2\left(-5\right)}}{2\cdot \:2}$

Apply the rule
$\sqrt{7^2+2\cdot \:4\cdot \:5}$

7^2 =49
$=\sqrt{49+2\cdot \:4\cdot \:5}$

Multiply
$\sqrt{49+40}$

Add
$\sqrt{89}$

$=\frac{-7-\sqrt{89}}{4}$

Final solution:
$x=\frac{-7+\sqrt{89}}{4},\:x=\frac{-7-\sqrt{89}}{4}$
