Answer 1

Step-by-step explanation:

Given: Length of line segment 7.6 cm and ratio 5 : 8 i.e., m : n.

Step-by-step Construction:

Step 1: Draw a line segment AB of length 7.6 cm.

Step 2: Draw any ray AX, making an acute angle with AB.

Step 3: Locate 13 ( = m + n ) points on AX so that.

Step 4: Join.

⇒ AC = 2.9 cm and CB = 4.7 cm.

Answer 2

Step-by-step explanation:

$ad^2(\frac{ax}{b}+\frac{2c}{d})x + bc^2$

$at (\: x =-\frac{bc}{ad})$

$ad^2(\frac{a}{b}*\frac{-bc}{ad}+\frac{2c}{d})(\frac{-bc}{ad})+bc^2$

$ad^2(\frac{-abc}{abd}+\frac{2c}{d})(\frac{-bc}{ad})+bc^2$

$ad^2(\frac{-c}{d}+\frac{2c}{d})(\frac{-bc}{ad})+bc^2$

$=ad^2(\frac{c}{d})(\frac{-bc}{ad})+bc^2$

$=ad^2(\frac{-bc^2}{ad^2}) + bc^2$

$= -bc^2 + bc^2$

$= 0$

$x=-\frac{bc}{ad} \: is \: satisfying \: the \: eq.$

$So , it's \: a \: solution \: of \: this \: eq.$
