The correct answer among the choices given is the second option. A line segment is precisely defined using the undefined terms point and plane. These three terms are undefined terms in geometry. A point has no dimension. A plane has no thickness but extends at all directions. A line has no thickness but extends in one dimension.

Step-by-step explanation:

130 ÷ 100 = 1.3

1.3 × 48 = 62.4

580 ÷ 100 = 5.8

5.8 × 27 = 156.6

458 ÷ 100 = 4.58

4.58 × 132 = 604.56

Answer:

2i and -2i

Step-by-step explanation:

I'll change u to x to be easier to understand.

x^2 = -4

sqrt(x^2) = sqrt(-4)

sqrt(-4) = 2i, or -2i

Hello everyone can you answer this for me? What is A in the equation attached? Please and thank you.

lapo4ka [179]

Answer:

a = 6

Step-by-step explanation:

Hello!

Solve:

4(3a - 4) = 56
3a - 4 = 14 (factoring out 4)
3a = 18 (adding 4 to both sides)
a = 6 (dividing by 3)

Another way:

4(3a - 4) = 56
12a - 16 = 56 (distributive property)
12a = 72 (moving like terms)
a = 6 (dividing by 12)

Distributive Property of Multiplication:

The process of distributing the outside factor to the terms in the parenthesis.

Example:

$4(3a - 4)\\\\4(3a) - 4(4)\\\\12a - 16$
