The tools that Greeks limit themselves to in their formal geometric constructions are straight edge and compass. Therefore, A and B are the correct answers.

Geometric construction is the process of drawing a geometrical figure using two geometrical instruments, a compass, and a ruler.

Compass and straight edge were the tools that were used by Greeks in their formal geometric construction.

During earlier Greek times, simple geometric tools were used like compass and straight edge to draw something. Rulers and other tools came to use much later in time.

Therefore, A and B are the correct answers.

Answer:

80000bacterias

Step-by-step explanation:

Volume of the bedroom= length ×width× height

Given

Length = 2m

Width = 4m

Height= 2.5m

Volume of the bedroom= 2×4×2.5

Volume of the bedroom = 20m³

Given that;

4000bacterias = 1m³

x bacteria = 20m³

Cross multiply

x =4000×20

x =80000

Hence 80000 bacteria's are present in Bill's room

A. (–4 + i) + 4i = –4 + (i + 4i)

Step-by-step explanation:

edge2020

Have a great day y'all :)

(–4 + i) + 4i = –4 + (i + 4i) is the associative property of addition. Thus, option A is correct.

According to the associative property of additionally, whenever at least three figures are added together, the outcome is unaffected by the sequence in which the individual numbers are added.

In the first given condition is is stated:

(–4 + i) + 4i  = –4 + (i + 4i)

-4 + i + 4i = -4 + i + 4i

5i - 4 = 5i - 4

As the LHS = RHS, the property is said to be valid for the associative property of addition.

Therefore, option A is the correct option.

Which equation shows an example of the associative property of addition?

(–4 + i) + 4i = –4 + (i + 4i)

(–4 + i) + 4i = 4i + (–4i + i)

4i × (–4i + i) = (4i – 4i) + (4i × i)

(–4i + i) + 0 = (–4i + i)
