Answer:
m = n = 2
Step-by-step explanation:
(m + n√2)(1 - √2)² = -2 + 2√2
(m + n√2)(1 - 2√2 + 2) = -2 + 2√2
(m + n√2)(3 - 2√2) = -2 + 2√2
3m - 2m√2 + 3n√2 - 4n = - 2 + 2√2
(3n - 2m)√2 + 3m - 4n = 2√2 - 2
3n - 2m = 2
4n - 3m = 2
3n - 2m = 4n - 3m
n = m
4n - 3n = 2
n = 2
m = 2

Answer:
x= −20
Step-by-step explanation:
Let's solve your equation step-by-step.
−3(x+9)=33
Step 1: Simplify both sides of the equation.
−3(x+9)=33
(−3)(x)+(−3)(9)=33(Distribute)
−3x+−27=33
−3x−27=33
Step 2: Add 27 to both sides.
−3x−27+27=33+27
−3x=60
Step 3: Divide both sides by -3.
−3x
−3
=
60
−3
x=−20
Answer:
x=−20
