Remember you can do anyting to an equation as long as ou do it to both sides
-6x+4=-50
minus 4 both sides
-6x=-54
divide both sides by -6
x=9
5x+6=-44
minus 6 both sides
5x=-50
divide both sides by 5
x=-10
-3(7+6x)=-201
normally you would distribute (that works) but it's easier to divide both sides by -3
7+6x=67
minus 7 both sides
6x=60
divide by 6 both sides
x=10
The radius of the donut is 3.14
Planet A, because 7 x 10 > 5 x 10, the 28 is also bigger than 26. The numbers means 10 x 10 x 10 x 10... and so on to 28 or 26 (whatever the number is)
Answer: The answer will probabily be "undfined" or "error"
Step-by-step explanation: firtst u need to find the dot product of both a and b (a.b).
then the magnitude of both (√a ,√b)
then u substitute them into the equation
∅=cos-1(a.b/√a x √b)
u will find it to be error bcoz it will be (0/√3 x 0)
