Answer:
17
Step-by-step explanation:
SQ bisects TSR into TSQ and RSQ
TSR=84
Half of 84 is 42.
RSQ=3x-9=42
3x-9=42
x=17
4y + x = -12
4y +x (-x) = -12 (-x)
4y/4 = (-12 - x)/4
y = -3 - (x/4)
hope this helps

Answer:
series is 15, 75, 375, 1875, 9375, 46875, 234375
Step-by-step explanation:
r=5
an = 234,375
n = 7
a1 = ?
a1 = an /rn-1
a1 = 234,375 /57-1
a1 = 15
a2 = 15*5 = 75
a3 = 15*25 = 375
a4 = 15*125 = 1875
a5 = 15*625 = 9375
a6 = 15*3125 = 46, 875
a7 = 15*15,625 = 234,375
Hence series is 15, 75, 375, 1875, 9375, 46875, 234375
