**Answer:11**

**Step-by-step explanation:**

(x-3) = 8

+3 +3

x = 11

**Answer:**

Side TV = 16

**Step-by-step explanation:**

WX is half the value of TV

to solve we have to set up an equation

21-5x=10x-2

because side WX is only have of side TV we have to multiple its side by 2 so now we have

21-5x=20x-4

step 1 add 4 to each side

25-5x=20x

step 2 add 5x to each side

25=25x

step 3 divide each side by 25

x=1

then we plug in x as 1 for side TV and get

21-5 which is equal to 16

**Answer: 2676**

**Step-by-step explanation:**

**223 x 12 = 2676**

**This is because 223 12 times equals 2676.**

***I will attach my work for the problem so you can see the solving process more clearly :).**

**Hope this helps :).**

The answer is:

The reason is:

bottom one is a square prism. the volume formula is l x w x h. 9 x 9 x 9

square prism : 729

then the top one is a triangular prism. which is 1/2b x a x a

so 3.5 x 9 x 9

triangular prism: 283.5

then add these 2 numbers

1012.5

You can multiply 3*5*7=105 and any multiple of 105 will have those as prime factors since they will be divisible by them.
