46.6 feet
Step-by-step explanation:
P = 2ℓ + 2w
P = 2(ℓ + w)
P = 2(15.5 + 7.8)
P = 2(23.3)
P = 46.6 feet
Answer:
–x + 5 = 5x
Equation A: y = –x + 5 Equation B: y = 6x – 2
x2 - 4x - 21
Yes it is right
r=1/2
the geometric sequence is being multiplied by 1/2 every time
28/2=14
14/2=7
7/2=3.5 and so on
