Answer:
a positive number
Step-by-step explanation:
-(-) = +
for example, -1 * -1 = 1
Answer:
a = sqrt(c^2 - b^2)
see image.
Step-by-step explanation:
If you square both sides of the equation, you get the Pythagorean Theorem back again.
c = sqrt(a^2 + b^2)
c^2 = a^2 + b^2
Solve for a means to get a all by itself on one side of the equation. Subtract b^2 and then take the square root. See image.
Answer:
I think the answer should be Mat A cause it has more space.
