Which expression can you simplify by combining like terms? clear check 6d2+5cd−3dc+86d2+5cd-3dc+8 12c2−8d2c+3dc+412c2-8d2c+3dc+4 7d2−3c2+6d−c7d2-3c2+6d-c 16c2+8cd+7c−8d

Step-by-step explanation:

you can use the algebraic expression

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

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
