The perimeter of the triangle is 42. Find the length of all the sides.

iragen [17]

<h3>Given :-</h3>

Perimeter of triangle = 42

Side 1 of triangle = (x + 4)

Side 2 of triangle = (3x + 8)

Side 3 of triangle = (5x + 6)

Length of sides

<h3>Explanation:</h3>

So to find length of sides we have to find the value of x.We can find value of x , by this formula:

$\\ \\$

$\bigstar \boxed{ \rm perimeter \: of \triangle \: = side_1 + side_2 + side_3}$

$\\ \\$

So:-

$\\$

$\dashrightarrow \tt perimeter \: of \triangle \: = side_1 + side_2 + side_3 \\$

$\\ \\$

$\dashrightarrow \tt 42 = (x + 4) + (3x + 8)+( 5x + 6) \\$

$\\ \\$

$\dashrightarrow \tt 42 = x + 4+ 3x + 8+5x + 6 \\$

$\\ \\$

$\dashrightarrow \tt 42 = x + 3x+5x+ 4 + 8 + 6 \\$

$\\ \\$

$\dashrightarrow \tt 42 = 9x+ 4 + 8 + 6 \\$

$\\ \\$

$\dashrightarrow \tt 42 = 9x+ 18\\$

$\\ \\$

$\dashrightarrow \tt 42 - 18 = 9x \\$

$\\ \\$

$\dashrightarrow \tt 24 = 9x \\$

$\\ \\$

$\dashrightarrow \tt 9x = 24 \\$

$\\ \\$

$\dashrightarrow \tt x = \dfrac{24}{9} \\$

$\\ \\$

$\dashrightarrow \bf x =2.67 \{approx \}\\$

$\\ \\$

Side 1 of triangle = (x + 4)
Side 1 of triangle =2.67 + 4
Side 1 of triangle = 6.67

Side 2 of triangle = 3x + 8
Side 2 of triangle = 3 × 6.67 + 8
Side 2 of triangle = 20.01 + 8
Side 2 of triangle = 28.01

Side 3 of triangle = 5x + 6
Side 3 of triangle = 5 × 2.67 + 6
Side 3 of triangle = 13.35 + 6
Side 3 of triangle = 19.35

Shawna and her best friend Keisha go shopping. The function p(t) = 3x +2x-4x2+ 21 represents how much money each girl spent base

NNADVOKAT [17]

Answer:

$\$30$

Step-by-step explanation:

we have

$p(t)=3x+2x-4x^{2}+21$

<em>Find the amount of money that each girl spent</em>

For t= 2 hours

$p(2)=3(2)+2(2)-4(2)^{2}+21$

$p(2)=10-16+21$

$p(2)=\$15$

<em>Find the amount of money that they spend together</em>

Multiply by 2 the amount of money that each girl spent

$(2)\$15=\$30$

Use lagrange multipliers to find the shortest distance, d, from the point (4, 0, −5) to the plane x y z = 9.

zlopas [31]

One function you would be trying to minimize is
<span>f(x, y, z) = d² = (x - 4)² + y² + (z + 5)² </span>

<span>Your values for x, y, z, and λ would be correct, but </span>
<span>d² = (20/3 - 4)² + (8/3)² + (-7/3 + 5)² </span>
<span>d² = (8/3)² + (8/3)² + (8/3)² </span>
<span>d² = 64/3 </span>
<span>d = 8/sqrt(3) = 8sqrt(3)/3</span>
