Contact [7]

Answer:

3pf² - 21p²f + 6pf - 42p²

= 3pf² + 6pf - 21p²f - 42p²

= 3pf(f +2) - 21p²(f + 2)

= (3pf - 21p²)(f +0 2)

Answer: (3pf - 21p²)(f + 2)

The length of the line segment joining the midpoints of sides AB and BC of the parallelogram ABCD is 10. Find the length of diag

solniwko [45]

Answer:

The length of the diagonal AC=20 cm.

Step-by-step explanation:

From ΔOBP and ΔABC, we have

$\frac{OB}{AB}=\frac{BP}{BC}$ ( O and P are mid points)

∠B=∠B(Common)

Therefore, by SAS rule,

ΔOBP is similar toΔABC

Thus, $\frac{OB}{AB}=\frac{OB}{2OB}=\frac{1}{2}$

⇒ $\frac{OP}{AC}=\frac{1}{2}$

⇒ $AC=2{\times}OP$

⇒ $AC=2{\times}10$

⇒ $AC=20 cm$

Thus, the length of the diagonal AC=20 cm.
