What is the longest line segment that can be drawn in a right rectangular prism that is 14cm​ long, 13cm​ wide, and 11cm​ tall?
vlabodo [156]

The longest line segment that can be drawn in a right rectangular prism that is 14cm long, 13cm wide and 11cm tall is 19.1cm.

<h3>What is a right rectangular prism?</h3>

A right rectangular prism is a three dimensional solid shape formed by 6 rectangles.

it is also called the cuboid.

Analysis:

The diagonal of the face of the prism with dimensions 14cm long and 13cm wide is the longest line segment that can be drawn.

Since rectangles have 90° on each vertex, we can use Pythagoras theorem to calculate for the length of the diagonal.

(diagonal)^{2} = (length)^{2} + (width)^{2}

(diagonal)^{2} = (14)^{2} + (13)^{2}

                 = 196 + 169 = 365

 (diagonal)^{2} = 365

diagonal = \sqrt{365} = 19.1cm

In conclusion, the length of the longest diameter is 19.1cm

What are the solutions to 2x^2-3x-5=0
olasank [31]
Well you have to factor first factoring gives you two value that you can multiply and get you a broken down version of that
you can do it two ways using the quadratic formula to factor or if you're really good at factoring just do it mentally (2x-5)(x+1)=0
for the mental way of doing the factors just set both 2x-5 equal to zero and x+1 = to zero
2x-5=0
2x=5
x= 5/2

x+1=0
x=-1

therefore the solutions are x = 5/2,-1
but if you want to learn how to do it mentally and with the quadratic function formula
let me know
