Answer:
39
Step-by-step explanation:
∑ ( from n = 1 to n =5 ) 3 · ( -2 ) ^( n -1 )
a 1 = 3 · ( -2 ) ^0 = 3
a 2 = 3 · ( - 2 ) = - 6
a 3 = 3 · 4 = 12
a 4 = 3 · ( - 8 ) = - 24
a 5 = 3 · 16 = 48
3 - 6 + 12 - 24 + 48 = 33
Answer: C ) 33
17²-8²=225
√225= 15
therefore both x and y are 15 ft
4-(6x + 5) = 7 - 2(3x + 4)
Distribute: 4 - 6x - 5 = 7 - 6x - 8
Combine like terms (constants): -1 - 6x = -1 - 6x
Add 1 to both sides: -6x = -6x
Divide both sides by -6: x = x
Hope this helps!
