Answer: B
Step-by-step explanation:
Oki so I know this becaue I study to much and because if there was an answer saying this : y=6x+3 it would be wrong because it is adding to the constant
So y=6x is proportinal because it is allways constant. I forgot this was an example sorry.
Answer:
Step-by-step explanation:
One
v^2 - 16
This formation is called the difference of squares. That's because there are 2 squares v^2 and 16. The key to this question is the minus sign.
The square root of v^2 = v
The square root of 16 = 4
You get (v + 4)(v - 4)
Let's see what happens when you expand it.
- v*v = v^2
- v*(-4) = - 4v
- v*(4) = 4v
- 4*-4 = - 16
Look what happens when you add these 4 terms together.
- v^2 - 4v + 4v - 16
- v^2 - 16
is what is left. The two middle terms cancel out.
Two
This one is a perfect square
w^2 + 16w + 64
(w + 8)(w + 8)
Notice both factors are the same. You might wonder how I new that.
w^2 is a perfect square so take the square root. .... v
64 is a perfect square so take the square root ..... 8
Now you have to work backwards to see if it is right.
- w*w = w^2
- w*8 = 8w
- 8*w = 8w
- 8^2 = 64
Adding you get w^2 + 16w + 64 which is what you started with.

Answer:
x=0
Step-by-step explanation:
Answer:
the answer should be 3146 because you have 11 cm for both length and width and you have also 11cm height but there is also 15 cm height for the triangle so if you times all of them together it should give you 3146
