Answer:
31x³-60x²+7x-75
Step-by-step explanation:
(30x³-49x³+7x)+(50x³-60x²-75)
(-19x³+7x)+(50x³-60x²-75)
-19x³+50x³+7x-60x²-75
31x³-60x²+7x-75
A + B + C = 476
A = 3B + 6
C = B + 45
now its just a matter of subbing..
A + B + C = 476
(3B + 6) + B + (B + 45) = 476...combine like terms
5B + 51 = 476
5B = 476 - 51
5B = 425
B = 425/5
B = 85 <== team B scored 85
A = 3B + 6
A = 3(85) + 6
A = 255 + 6
A = 261 <=== team A scored 261
C = B + 45
C = 85 + 45
C = 130 <=== team C scored 130
Yo sup??
We have to apply trigonometry ie cosine formula
cos44=RS/RQ
RS=RQ*cos44
=7.2
Hope this helps
