The ratio of the sides of a triangle is 20: 19: 20. if the perimeter of the triangle is 354 inches, what are the lengths of all three sides.

20*6 - 120

20*6 = 120

19 * 6 = 114

Step-by-step explanation:

Call x the scale factor.

20x + 19x + 20x = 354       Add the left side together.

59x = 354                           Divide by 59

59x/59 = 354/59                Combine and cancel

x = 6

The lengths of the sides are

20 * 6 = 120

19 * 6 =  114

20 * 6 = 120

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3
