-15 = - 5u + 2 ( u + 3 )

u = 7

Step-by-step explanation:

First do distributive property to 2(u+3) this makes it -15=-5u+2u+6.

Then combine like terms: -15= -3u +6 (the positive u's cancel out the negative u's)

get U by itself by subtracting 6 from both sides: -21= -3u

Divide both side by -3: -21/-3 = -3u/-3

Answer is 7= u

Check your Plug in 7

-15 = -5(7)+ 2(7+3)

-15= -35 + 14+6

-15= -35+20

-15=-15

Step-by-step explanation:

-15=-5u+2(u+3)

-15= -5u+ 2u+6

-15= -3u+6

-6

-21=-3u

U= 7 I gotchu

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
