To the nearest tenth, what is the length of QR

|QR| = 17.6

Step-by-step explanation:

To answer this we need to show that the triangles are similar or to assume that they are similar.

Note the following:

1.  The ratio of the longest sides is 12.5 to 25.0, or 1/2;

2.  The ratio of the shortest sides is 5.2 to 10.4, or 1/2

Therefore the ratio of the longer legs is 8.8 to QR, also equal to 1/2

 8.8        1

=

  QR       2

Cross-multiplying, we get |QR| = 17.6

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

probably .5

i can on others if necessary.
