Let x = the shorter leg
2x + 6 is the longer leg
2x + 9 is the hypotenuse
We now do the Pythagorean Theorem of


Multiply out to get:

The

will cancel out each other when you combine like terms to get all the terms on one side of the equal sign.
Combine like terms with the rest to end with

Factor this to get

then set each factor equal to zero.
You end up with two solutions, x = 15 and x = - 3
HOWEVER distance cannot be measure in negatives so that answer will not work so x = 15. Now plug into our given information.
The short leg is 15 cm long.
The longer leg of 2(15) + 6 = 36 cm long
The hypotenuse of 2(15) + 9 = 39 cm long.
You can check your answers by plugging them into the Pythagorean Theorem again.
Answer:
-7/2
Step-by-step explanation:
Slope equals rise (vertical or y axis) over run (horizontal or x axis). So you need to find two points on this line that cross directly where the grid lines cross. If you look closely, the line seems to cross directly at ( -6, 3 ) and again at ( -4, -4). So the rise values (y axis) are 3 and -4 which is a total of 7 units apart.
The run values are -6 and -4 which is a total of 2 units apart.
So your slope with be 7/2 but since it slopes downward to the right, it is a negative slope.
The answer would be negative 7/2
A is the answer
divide 0.5/ 0.1
The answer is going to be <span>B. 160/8. divide 160/8 to get 20 pages so he reads 20 pages each day and you can check by multiplying 20*8=160</span><span />
