Explanation:
B is a random sample, while A, C, and D are biased.
Answer:
3x - 3
Step-by-step explanation:
f(x) + g(x)
(2x + 2) + (x - 5)
3x - 3
1)Simplify 3\times 1043×104 to 312312
312-5\times 102312−5×102
2)Simplify 5\times 1025×102 to 510510
312-510312−510
3)Simplify
-198−198
Because the opposite sides are congruent, so are the angles.
4x+20=40
subract 20 from both sides
4x=20
divide by 4 on both sides
x=5
(2(3x4))+(2(4x8))+(2(3x8)) = 24+64+48 = 136
Answer: C
