we know that
1 ft--------> is equals to 12 in
the ramp is 12 inches tall----------> 1 ft tall
A ramp measures------------------> 6 ft long
applying the Pythagorean theorem
c²=a²+b²
where
c-----> 6 ft long
a----> horizontal distance
b-----> 1 ft tall
a²=c²-b²------> a²=6²-1²-----> a²=35------> a=√35------> a=5.92 ft
the answer is
5.92 ft
I don't think that you can. Integers are either positive or negative real numbers without decimals, so there isn't anything to simplify.
If you add 2 odd numbers together eg. 5+5 it would become an even number eg. 10.
If you add 2 even numbers together eg. 60+60 it would stay as an even number eg.120.
The product is basically the same thing as that but instead of adding the same number twice, you multiplying the number with 2 which is the same as adding two of the same numbers.
