Solve the equation for the letter L: V = LWH

Answers

$LWH=V\qquad\text{divide both sides by}\ WH\neq0\n\n\boxed{L=(V)/(WH)}$

Answer:

L = V / WH

Step-by-step explanation:

Solve for L: V = LWH

To solve, all you have to do is get L on its own on one side.

Because the only operation used in this equation is multiplication, only one operation is needed to solve it: division. Just divide both sides by WH to isolate L.

V / WH = LWH / WH

V / WH = L

in class, matthew stated "i think that a negative is like an opposite. That is why multiplying a negative times a negative equals a positive. The opposite of negative is positive, so it is just like multiplying the opposite of a negative twice, which is two positives." Do you agree or disagree with this statement? What would you say in response to him?

Answers

Answer: Yes, I agree with this statement.

Step-by-step explanation:

Yes, I agree with this statement.

Whenever we multiply two negative numbers, we get a positive number.

As two negatives makes a positive.

Negative is just like an opposite.

Opposite of 4 is -4.

and negative of 4 is also -4.

The opposite of negative is positive.

i.e. opposite of -4 is 4.

So, Negative is always treat as opposite.

Yes and no. A negative number and it's opposite are 'integers.' Yes, a negative and a negative multiplied together give you a positive. The two negative signs cancel out making it positive. But no, a positive and a positive multiplied together do not give you a negative. When you subtract positive numbers you can get a negative, but not when multiplying. If you were to do a positive times a negative it would be negative because the positive can't cancel it out. Example: -3 · -3 = 9. [] 3 · 3 = 9. [] -3 · 3 = -9. Other than the positive number part, the statement is true about the negatives. I hope that helped!

because 20% off of 149.99 is 30$ so, 150-30=120

Algebra tiles to prove that 4 + 8x and 4(2x+1)

Answers

not sure what algebra tiles are

not sure how to absolutely prove
I can prove it works at least most of the time by subsitute ing number for x

remember that 0,1,2 have special properties and are not very good for subsituting so
try 4
4+8(4)=4(2(4)+1)
true or false?
4+8(4)=4(2(4)+1)
multipily
4+32=4(8+1)
36=4(9)
36=36
this is treu at least for the number 4
another way is to believe in the distributive property where
a(b+c)=ab+ac so then
4(2x+1)=4(2x)+4(1)=8x+4=4+8x

4 + 8x

Now, see if the simplified form of 4(2x + 1) is equal to that.

4*2x = 8x
4*1 = 4

4 + 8x = 4 + 8x Correct
