Answer:
3rd and 4th option
Step-by-step explanation:
-1 times -1 is 1 and multiply that by another -1 and you get -1
-1 times -1 is 1 and you do that twice in the last option so that would be 1 and then multiply that by-1 and you get -1.
Answer:
7.3
Step-by-step explanation:
In order to find the hypotenuse, we just need to use the Pythagorean Theorem.
Remember, that this theorem only works for right triangles.
This theorem states that a^2+b^2=c^2
This is where a and b are legs of the triange, and c is the hypotenuse.
Knowing this, we can plug our values in.
6.4^2+3.5^2=c^2
Simplify.
41.344+12.25=c^2
53.594=c^2
Root both sides.
c=7.32 (about)
Round that to tenths.
c=7.3
