Answer:

x = 2 + 5i√2 / 6 and x = 2 - 5i√2 / 6

Step-by-step explanation:

If this isn't right, I'm sorry. Also, you can put x = 2 ± 5i√2 /6 to make it shorter and not have two answers. Hope this helps :)

what is the formula for calculating the length of the space diagonal of a right rectangular prism on the basis of the prism's le

Lady bird [3.3K]

The diagonal of a right rectangular prism is the line that connect opposite vertices. In other word is the distance from corner to corner in the right rectangular prism. Since the diagonal of a right rectangular prism is the hypotenuse of a right triangle, we are going to use a variation of the Pythagorean theorem to find it. In essence, we just need to add another dimension to the Pythagorean theorem; in this case the height of our prism:

We can conclude that the formula to calculate the length of the diagonal of a right rectangular prism is: $d= \sqrt{l^2+w^2+h^2}$
where
$d$ is the length of the diagonal.
$l$ is the length of the rectangular base of the prism.
$w$ is the width of the rectangular base of the prism.
$h$ is the height of the prism.

JulsSmile [24]

Answer:

$\large\boxed{\dfrac{11}{4}x+8}$

Step-by-step explanation:

$\left(-\dfrac{11}{4}x+3\right)-2\left(-\dfrac{11}{4}x-\dfrac{5}{2}\right)\qquad\text{use the distributive property}\\\\=-\dfrac{11}{4}x+3+(-2)\left(-\dfrac{11}{4}x\right)+(-2)\left(-\dfrac{5}{2}\right)\\\\=-\dfrac{11}{4}x+3+\dfrac{22}{4}x+5\qquad\text{combine like terms}\\\\=\left(-\dfrac{11}{4}x+\dfrac{22}{4}x\right)+(3+5)\\\\=\dfrac{11}{4}x+8$
