Answer:
f(x) is even
Step-by-step explanation:
f(x) = 3
f(-x) = 3
f(x) = f(-x)
Answer:
x=-34
Step-by-step explanation:
x-44=-78
Add 44 to each side
x-44+44 = -78+44
x = -34
The answer is 2.6. I could be wrong.
Answer:
x = 38
∠P = 26º
Step-by-step explanation:
The sum of the angle in a triangle is 180
x + (x + 78) + (x - 12) = 180
Combine like terms
3x + 66 = 180
Subtract 66 from both sides
3x = 114
Divide both sides by 3
x = 38
-----------------------
∠P = x - 12
∠P = 38 - 12
∠P = 26º
Answer:
B
Step-by-step explanation:
2 walls are 30 x 9 and 2 walls are 20 x 9 and there are 4 units
30 x 9 = 270, 20 x 9 = 180
4(2)(270) + 4(2)(180) = 3600, so the answer is B
