Find the surface area of this net

Mathematics
1 answer:
Stells [14]3 years ago
6 0

You always have to find the LSA (lateral surface area) first.

(which is the shape's area combined w/out the bases.)

rectangle A would be 60 and so would rectangle C

rectangle B would be 96

if u add them all together that would be 12.5

Now you have to find the TSA (total surface area).

(which is the TOTAL net combined w/ bases)

the bases would be 7.5

7.5 x 2 is 12.5

Add the LSA and the TSA

216+12.5=228.5

<u>so the overall answer would be 228.5cm</u>

i hope this helps!!

Solve for x <br>3(x - 2) = 6x - 12<br>​
nalin [4]

Answer:

The answer is 2

Step-by-step explanation:

Here's how I got it:

3(x - 2) = 6x - 12

Multiply 3 times x and 3 times 2, this is what you would get

3x - 6 = 6x - 12

Then, subtract the lowest x with the bigger X, this way you would have x on one side:

3x - 6 = 6x - 12

-3x        -3x

This is what you should have after this:

-6 = 3x - 12

Now, to get the variable (letter that represents a number) by itself, you have to add 12 to both sides like this:

-6 = 3x - 12

+12        +12

You would get this:

6 = 3x

Finally, you have to get x by itself, so you have to divide 3 on both sides like this

6/3 = 3/3 x

That's why, your answer is 2
