На координатной плоскости даны точки А (-10; -18), В (35; 15), С (-5; 40) и D (1; -20). Расположите данные точки по порядку в соответствии с номерами координатных четвертей: I, II, III, IV.

Step-by-step explanation:

The problem is

In the coordinate plane, points A (-10; -18), B (35; 15), C (-5; 40) and D (1; -20) are given. Arrange these points in order according to the numbers of the coordinate quadrants: I, II, III, IV.

First of all, we need to analyse the signs of each variable at each quadrant.

Quadrant I: x-variable is positive and y-variable is positive.

Quadrant II: x-variable is negative and y-variable is positive.

Quadrant III: x-variable is negative and y-variable is negative.

Quadrant IV: x-variable is positive and y-variable is negative.

Now, according to the description above, the order of the given coordinates is

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

answer: it's upside down and i can't read it
