We don't have enough information to solve this problem; it needs to be equal to something.

This is a multiplication problem. We multiply the miles/day by the number of days.

1.9 * 7 = 13.3

The possible base and height lengths will all be factors of 52, since they have to multiply to equal 52.

Possible integer base and height lengths are:

1 * 52

2 * 26

4 * 13

We can't find out the exact answer; we don't have enough information about the parallelogram. If we had one side length, we could figure out the other.

To clarify: when you convert 2/3 to a denominator of 6, you do not multiply by 2, but rather 2/2. When you multiply fractions, you multiply the denominater by the denominator and the numerator by the numerator.

If you were to multiply 2/3 by 2, you would come out with a product of 4/3 or 1 1/3, because 2 is 2/1.

Another note: when you multiply on computers, you probably want to use asterisks (*) for multiplication.

Math, a shortening of mathematics, is defined as the science of numbers, quantities, and shapes and the relations between them (Merriam Webster online.)

Let's call our three integers "s", "m", and "l", "s" being the smallest and "l" being the largest.

Before looking at the equation, we know:

s + 1 = m

m + 1 = l

So the equation you gave me was:

3m = s + l + 5

The easiest way to do this is the substitution method: Since we know what l equals, and we know what m equals, we can substitute them in the third equation.

Let me show you:

3m = s + l + 5

We can replace l with m + 1, since that's what it equals.

3m = s + (m + 1) + 5

At this point, since we already have 2 m's, it will be easier to substitue something for s.

We can find out what s equals by modifying the equation s + 1 = m.

Taking one away from each side will make the equation s = m - 1

So now we know what s equals, and we can substitute it as well:

3m = (m - 1) + (m + 1) + 5

Going on:

3m = m - 1 + m + 1 + 5

3m = 2m + 5

Now just need to isolate the variable m. The easiest way to do this is by subtracting 2m from each side:

(1)m = 5

m = 5

Now that we know what m equals, we can substitute in the other two original equations:

s + 1 = m

s + 1 = 5

Subtracting one from each side:

s = 4

And the next one:

m + 1 = l

5 + 1 = l

6 = l

We now know our three numbers: 4, 5, & 6.

We just have to replace "x" with 6.

So instead of (3x - 1)

We have: (3(6) - 1)

3 * 6 = 18, so (18 - 1)

And our final answer is 17.

To start off, you must know anything to the power of zero equals 1.

So 5^0 = 1

And we have: 3 + 1 = 4

Using distributive property, we can get: (2x)^2 - (3)^2

Then: 2x^2 - 9

And that's about all I can do.
