Answer:
Step-by-step explanation:
x^2+120=0 can be rewritten as x^2 = - 120. Taking the square root of both sides, we get x = plus or minus i*√120 = plus or minus i*√4√30, or
x = plus or minus i*2√30
So the correct answer choice here is "None of the above."
Answer:
164.22 liters
step explanation:
(46 cm) * (85 cm) * (42 cm) =
164.22 liters
To find x:
Subtract 10 on both sides.
10 + 2x = 90
-10 -10
Divide 2 on both sides.
2x = 80
--- ---
2 2
This would get x alone.
x = 40
Check:
10 + 2(40) = 90
10 + 80 = 90
90 = 90
The value of x is 40. The angle degree of it is 80 when you multiply 2 by 40.
Answer: Is this a question? Or statement Yes they can be angles
Step-by-step explanation:
It is a parallelogram, so opposite angles are congruent.
4x = 100°
x = 25°
Sum of angles in a parallelogram is 360°.
360°-100°-100° = 160°
y = 160°/2 = 80°
