Answer:

$x=8\ in$

Step-by-step explanation:

we know that

If NO is parallel to KJ

then

Triangles LNO and LKJ are similar by AA Similarity Postulate

Remember that

If two figures are similar, then the ratio of its corresponding sides is equal

$\frac{LO}{LJ}=\frac{LN}{LK}$

substitute the values

$\frac{x-4}{x-4+x}=\frac{x-3}{x-3+x+2}$

$\frac{x-4}{2x-4}=\frac{x-3}{2x-1}\\ \\(x-4)(2x-1)=(x-3)(2x-4)\\ \\2x^{2}-x-8x+4=2x^{2}-4x-6x+12\\ \\-9x+4=-10x+12\\ \\10x-9x=12-4\\ \\x=8\ in$

If all the dimensions of a cube are doubled, then the new volume is___ times greater.

vichka [17]

The formula for finding the volume of a cube is $s^{3}$ , where s is the side length.

The formula for a cube with each side length doubled is $(2s)^{3}$ , or 8s.

If all the dimensions of a cube are doubled, then the new volume is eight times greater.
