√80 = √16 * √5  = 4√5

From the Pythagorean Theorem......b = √(34² - 16²)

Hint...your answer will be an integer > 25  but < 35

OK....

Here's how to convert 5 + 1/2 to an improper fraction......

First.......multiply the denominator  of the fraction, (2),  by the whole number (5).....this gives us 10. Add the "1" in the numerator of the fraction to this.....this gives us 11

Now......put this result (11) over the denominator of the fraction (2).....thus gives us 11/2.....and that's it!!!

I want you to try 8 + 2/3 yourself....just follow the above steps....let me know what you get.......

Once you have mastered this....we'll move on to multiplication of fractions (if that's giving you trouble, too)

It's no good in trying to do these problems if you're having trouble with the "basics".....

Just multiply all three things together, since W x L x H   = Volume

Hint ..... 7+ 1/2  =  15/2   and 17 + 3/4   =  71/4

Stuff^2.......

Apparently, for you.....Spelling doesn't seem to be much of a picnic, either......

Using y = mx + b and substituting in for y, m and x, we have

-4 = -6(2) + b

-4 = -12 + b     add 12 to both sides

8 = b   so, the equation is....

y =-6x + 8  or, in Standard Form, 6x + y  = 8

So

4 + 4 + 4 + N = 40  or, algebraically.....

3(4) + N = 40

12 + N = 40    subtract 12 from both sides

N = 28

And that's the number.....

To find out if this forms a right triangle......see if the following is true...

7^2 + 24^2   = 25^2    ???

If it is, we have a right triangle....
