Simplify the expression
4 + 2(6 + 1) +5(5-2)

33

Step-by-step explanation:

4+2(6+1)+5(5-2) = 4+12+2+25-10 = 16+2+15 = 18+15 = 33

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.

hope it you

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
