Remember
you can do anyting to an equaiton as long as you do it to both sidess
distributive property
a(b+c)=ab+ac
commutativ property
a+b=b+a
distribute
3(4x-2)=12x-6
12x-6=9+2x+5
add 6 both sides
12x+6-6=9+6+5+2x
12x+0=20+2x
minus 2x
10x=20
divide 10
x=2
Answer:
3-9/1-2=-6/-1=6
Step-by-step explanation:
y2-y1/x2-x1

V is the 3D region enclosed by S.
div(F)= <span>∂(x)/∂x + ∂(y)/∂y + ∂(10)/∂z = 2
</span>
<span>∫ = ∫∫∫ [V] div(F) dV = 2 ∫∫∫ [V] dV
Using cylindrical coords, ( rcos(θ), y, rsin(θ) ), dV=rdrdθdy
∫ = 2 ∫∫∫ rdrdθdy, [r=0,1], [θ=0,2π], [y=0,7−rcos(θ)] = 14π (easily integrated)</span><span>
