Since we have two possible pieces of information and 2 items to solve for, we know this is a system of equations.
Our first piece of information is that our shorter leg (s) is 2 feet shorter than our longer leg (l). This can be written as s=l-2.
Our second piece of information is that using the Pythagorean theorem that our shorter leg squared plus our longer leg squared is equal to our hypotenuse squared. This can be represented by s^2+l^2=10^2. Now we can solve.
We have already isolated for s in our first equation, so we can substitute l-2 in.
(l-2)^2+l^2=10^2
l-2+l=10
2l-2=10
2l=12
l=6
Now we can substitute in for s in our simpler equation
s=6-2
s=4
We now know that using our knowledge of systems of equations, the side lengths of this right angle triangle are 6 and 4.
Answer:
l
Step-by-step explanation:
The whole part will be the 4. The fraction part will be the decimal. That converts to the fraction 25/40. Therefore, 4.625 as a mixed number is 4 and 25/40.
False because 4x-3(5x-1) is -14x and 3+9x is 6x
The best and most correct answer among the choices provided by the first question is the first choice or letter A.
The expression above is an example of a numerical expression.
