Could you help me with the first one?

answer: 0+0=0

step-by-step explanation:

that is the only answer that can make 0

a - base

b - exponent

so,

the answer should be a. snail

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
