If C is between A and B, then answer the following if AB=40, AC= 2x+10, CB= 3x-5

Marat540 [252]

If C is between A and B, then, we can write the equation

$AB = AC + CB$

Substitute the value of AB and the expressions for AC and CB in terms of x.

$40 = (2x+10)+(3x-5)$

We can now solve for x.

$40-10+5= 2x+3x$

$35=5x$

Dividing by 5.

$7=x$

$AB=40$

$AC=2(7)+10$

$AC=14+10$

$AC=24$

$BC=3(7)-5$

$BC=21-5$

$BC=16$

Can some one help me. The QN is SIMPLIFY BY RATIONALISING DENOMINATOR.

WITCHER [35]

Answer:

$\frac{10}{3}$ - $\frac{2\sqrt{7} }{3}$

Step-by-step explanation:

Rationalise the denominator by multiplying the numerator/ denominator by the conjugate of the denominator

the conjugate of $\sqrt{7}$ + 5 is $\sqrt{7}$ - 5, hence

12 / ( $\sqrt{7}$ + 5) × ( $\sqrt{7}$ - 5 ) / ( $\sqrt{7}$ - 5)

= (12 $\sqrt{7}$ - 60 ) / - 18

= $\frac{10}{3}$ - $\frac{2\sqrt{7} }{3}$
