Answer:
x = 3
Step-by-step explanation:
8x - 12 = 4x
<em>subtract 4 from each side</em>
4x - 12 = 0
<em>add 12 to each side</em>
4x = 12
<em>divide each side by 4</em>
x = 3
Answer:
128°
Explanation:
1 = 4 because of vertical angles are the same
4 = 5 because of alternate interior angles are the same
5 = 8 vertical angles
8 = 9 alternate interior angles
9 = 12 vertical angles
180° = 12 + 11
11 = 180° - 52°
angle 11 = 128°
The expansion of the binomial:
( 2 x² + y² ) ^4 =
=
