Answer:
The answer is B (30)
Step-by-step explanation:
X = 3 and y = 6.
4(3) = 12
3(6) = 18
12 + 18 = 30
Answer:
4x·7
Step-by-step explanation:
Answer:
∠ a = 60° , ∠ b = 120°
Step-by-step explanation:
Supplementary angles sum to 180° then
x - 40 + x + 20 = 180 , that is
2x - 20 = 180 ( add 20 to both sides )
2x = 200 ( divide both sides by 2 )
x = 100
Then
∠ a = x - 40 = 100 - 40 = 60°
∠ b = x + 20 = 100 + 20 = 120°
Answer:
-42
Step-by-step explanation:
B)
2x - 3 = -6
-6 × 7 = (-42)
