What value of r is a solution to this equation?
-3 = 3(r + 10)
r = -11
r= -9

r=-11

Step-by-step explanation:

substitute -11 and -9 for r.

-3=3(r+10)

-3=3(-11 +10)

-3=-33+30

-3=-3

-3=3(r+10)

-3=3(-9+10)

-3=-27+30

-3=3

(that does not make sense, -3=3, so r would be -11.)

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
