In the figure, pq is parallel to rs. the length of rp is 8 cm; the length of pt
is 16 cm; the length of sq is 11 cm. what is the length of qt

QT = 22 cm.

Step-by-step explanation:

RP / PT = SQ / QT

8/16 =  11/ QT

1/2 = 11/QT

QT = 2*11

QT = 22 cm.

A. 22 cm

Step-by-step explanation:

By the Thales Theorem we know that: If we have two parallel straight lines and they cut other two ones, for example lines of a triangle then they produce proportional segments, which means:

RP is proportional to PT and SQ is proportional to QT, we can express that as:

RP/PT=SQ/QT

And we have:

RP is 8 cm

PT is 16 cm

SQ is 11 cm

Then:

8/16=11/QT

We have to calculate QT:

QT= (16*11)/8 =22cm

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to

it's
