Question: x-10<6-5x is it x<8/3 OR x<-8/3 help ;-;

Montano1993 [528]

You need to isolate/get x by itself in the inequality:

x - 10 < 6 - 5x Add 5x on both sides

x + 5x - 10 < 6 - 5x + 5x

6x - 10 < 6 Add 10 on both sides

6x - 10 + 10 < 6 + 10

6x < 16 Divide 6 on both sides to get x by itself

$x$ Simplify the fraction

$x$ So the 1st option

One diagonal of a cube has length 12. Compute the surface area of the cube.

arlik [135]

Answer:

The surface area of the cube is $288\ units^{2}$

Step-by-step explanation:

we know that

The length of a diagonal of a cube is equal to

$D=b\sqrt{3}$

where

b is the length side of a cube

In this problem we have

$D=12\ units$

$12=b\sqrt{3}$

solve for b

$b=\frac{12}{\sqrt{3}}\ units$

Simplify

$b=4\sqrt{3}\ units$

Find the surface area of the cube

The surface area of the cube is equal to

$SA=6b^{2}$

substitute the value of b

$SA=6(4\sqrt{3})^{2}=288\ units^{2}$
