-3a^2 - b^3 + 3c^2 - 2b^3......when a = 2, b = -1, and c = 3
-3(2^2) - (-1^3) + 3(3^2) - 2(-1^3) =
-3(4) -(-1) + 3(9) -2(-1) =
-12 + 1 + 27 + 2 =
-12 + 30 =
18 <==
Answer:

Step-by-step explanation:
The exponent of -8 tells you the most significant digit (6) goes in the 8th position to the right of the decimal point.
With some spaces to help in counting decimal places, the number is written ...

(-1,10), (2,1) , (0,7), (-2,1)
Answer:
∠ 3 = 55°
Step-by-step explanation:
∠ 2 and ∠ 7 are corresponding angles and are congruent, then
5x - 60 = 3x + 14 ( subtract 3x from both sides )
2x - 60 = 14 ( add 60 to both sides )
2x = 74 ( divide both sides by 2 )
x = 37
∠ 2 = 3x + 14 = 3(37) + 14 = 111 + 14 = 125°
∠ 2 and ∠ 3 are adjacent angles on a straight line and sum to 180° , so
125° + ∠ 3 = 180° ( subtract 125° from both sides )
∠ 3 = 55°
