25= 5(3X-4)^1/3<br> PLEASE HELP AND SHOW WORK!<br> THANKS SM

Effectus [21]

Answer:

$x=43$

Step-by-step explanation:

Given equation:

$25=5(3x-4)^{\frac13}$

Divide both sides by 5:

$\implies 5=(3x-4)^{\frac13}$

Cube both sides:

$\implies 5^3=((3x-4)^{\frac13})^3$

$\implies 125=(3x-4)^{\frac33}$

$\implies 125=(3x-4)^1$

$\implies 125=3x-4$

Add 4 to both sides:

$\implies 129=3x$

Divide both sides by 3:

$\implies x=43$

In a parallelogram a diagonal of the length 20 cm is perpendicular to one of the sides. Find the longer side of parallelogram if

vovangra [49]

If diagonals of a parallelogram are perpendicular to each other, this is a rhombus. A rhombus has all sides equal.
In the current scenario, the shorter rhombus is 20 cm long and has a perimeter of 80 cm

Side of rhombus = 80/4 = 20 cm
A quarter of rhombus is right angled triangle with hypotenuse being side of rhombus.
Half length of long diagonal = sqrt (20^2-10^2) = 17.32 cm
Length of longer rhombus = 17.32*2 = 34.64 cm
