Ais a proposed explanation for a set of observations. it leads to predictions that can be tested by additional observations or by experiments.

Hypothesis

Explanation:

Hypothesis is basically proposed for explaining the different set of the observation and phenomena. In mathematics, a hypothesis is a doubtful articulation which is upheld by all the accessible information and by numerous result outcome.

The most well known guess in science is the Riemann theory, which regardless of numerous proof, is provided by many related outcomes.

Hypothesis is a thought or clarification that you at that point test through examination and experimentation.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

30 units^2

area is l × w

the length is 3

and the width is 10
