A rectangle that is 2 inches by 3 inches has be scaled by a factor 7 what are the side legnths of the scaled copy? Shorter length?

Given :

A rectangle that is 2 inches by 3 inches.

To Find :

If the rectangle is scaled by a factor 7 what are the side lengths of the scaled copy.

Solution :

It is given that the rectangle is scaled by 7.

So , new length and breadth are also multiplied by 7.

New sides are 2×7 = 14 and 3×7 = 21 .

Therefore, the side length after scaling is 14 inches and 21 inches.

Hence, this is the required solution.

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
