4 + (14 - 12) = 4 + (12) = 16

A. 4 - (-14 - 2) = 4 - (-16) = 20. Not equivalent.

B. (4 - 14) - 2 = (-10) - 2 = -12. Not equivalent.

C. 4 - (-14) - (2) = 18 - 2 = 16. Equivalent.

D. 4 + 14 + (-2) = 18 + (-2) = 16. Equivalent.

E. - (-4 - 14) - 2 = - (-18) - 2 = 18 - 2 = 16. Equivalent.

Choices C, D, and E are all equivalent to the expression 4 + (14 - 2).

What are the true and false statements for If two planes intersect, then their intersection is a line. Include converse, inverse

KonstantinChe [14]

Answer and Step-by-step explanation:

Solution:

Statement:

If two planes intersect their intersection is a line.

Suppose that

P =if two planes intersect.

q = then their intersection is line.

¬p = if two planes do not intersect.

¬q = then their intersection is not a line.

Converse:

If two planes intersect their intersection is a line.

P → q

Inverse:

If two planes do not intersect, then their intersection is not a line.

¬p → ¬q

Contrapositive:

If two planes intersection is not a line, then they do not intersect.

¬q → ¬p
