Answer:

Hello! answer: 268

Step-by-step explanation:

When doing these you want to find each face separately then add them up so here are all the faces... 24 + 24 + 80 + 80 + 30 + 30 = 268 so 268 is our surface area! Hope this helps!

Answer:

268 cm²

Step-by-step explanation:

Surface area: The sum of all the areas of every side of the prism.

As a shortcut, you can find the three unique sides and multiply the number by 2 (because opposite sides of a rectangular prism are the same)

Find the surface area of:

8 by 10 side: 8 * 10 = 80

3 by 8 side: 3 * 8 = 24

3 by 10 side: 3 * 10 = 30

Add these measures together.

80 + 24 + 30 = 134

Multiply this number by 134.

134 * 2 = 268

Thus, the answer is 268 cm²

Solve x(x-1) (X-5) <=O​
lara [203]

Answer:

x <= 0 or  1 = < x <= 5.

Step-by-step explanation:

First we find the critical points:

x(x - 1)(x - 5) = 0

gives x = 0, x = 1 and x = 5.

Construct a Table of values:

               <u>  x < 0 </u>  <u>x = 0 </u> 0<u>< x < 1</u>  <u>1 =< x <= 5</u>     <u>x = 5</u>

x                  <0        0          >0             <0           0

x - 1             <0       -1           >0              <0           0

x - 5            < 0       0          > 0             <0           0

x(x-1)(x-5)    < 0      0          >0              <0          0 

So the answers are x =< 0 or  1 =< x <= 5.
