Answer: -18x to the second power+3x+1
Step-by-step explanation:
Answer:
∠ 1 = 105° , ∠ 2 = 75°
Step-by-step explanation:
Since the lines are parallel then
∠ 2 = 75° ( corresponding angle )
∠ 1 and ∠ 2 are adjacent angles and supplementary, thus
∠ 1 = 180° - 75° = 105°
81
(-9)(-9) is 81
Multiplying two negatives gives a positive
X2=16/25=0.64
,x=0.64^1/2
,x=0.8
