What the result of √[(-2a)^ 2]

1 answer:

3 0

If you take the square root of a number squared number then they cancel each other out and the number stays the same i.e. √[(4)^2] would equal 4.

In this problem the square root and numbered squared cancel out to leave the problem as -2a.

The solution of this problem is -2a

Suppose △PKN≅△BGH△PKN≅△BGH. Which other congruency statements are correct? Select each correct answer. △NKP≅△HBG△NKP≅△HBG △KPN≅△

NeTakaya

Answer:

△NPK≅△HBG; and △KNP≅△GHB

Explanation:

Using the given congruence statement, we can determine corresponding pieces of the triangles:

P corresponds to B; K corresponds to G; and N corresponds to H.

This means that △NKP≅△HGB, not HBG.

△KPN≅△GBH, not BHG.

△NPK≅△HBG; this is correct.

△KNP≅△GHB; this is correct.

Vesnalui [34]

5/4=x/20 just cross multiply 5x20 and 4 times x
100=4x divide both sided by 4
100/4=x divide

How can you find the conditional probability of A given B as the fraction of B's outcomes that also belong to A, and interpret t

liberstina [14]

The given fractions representing the conditional probability is P(A | B) = P(AnB)/P(B)

<h3>Conditional Probability</h3>

This is the probability that an event has happened given another event. If the two events are A and B, hence;

The conditional probability of A given B is expressed as:

P(A | B) = P(AnB)/P(B)

This given the fractions representing the conditional probability
