Hello :
PA = PB or PA² = PB²
(5-b)²+(4-2)² = (2-b)² + (5-2)²
(5-b)²+4 = (2-b)² + 9
25 -10b +b² + 4 = 4 -4b+b² +9
-6b = -16
b = 8/3
Step by step solution :
Step 1 :
Step 2 :
Pulling out like terms :
2.1 Pull out like factors :
2y + 8 = 2 • (y + 4)
Equation at the end of step 2 :
(0 - (4 • (4y - 10))) + 6 • (y + 4)
Step 3 :
Step 4 :
Pulling out like terms :
4.1 Pull out like factors :
4y - 10 = 2 • (2y - 5)
Equation at the end of step 4 :
(0 - 8 • (2y - 5)) + 6 • (y + 4)
Step 5 :
Step 6 :
Pulling out like terms :
6.1 Pull out like factors :
64 - 10y = -2 • (5y - 32)
Final result :
-2 • (5y - 32)
Ration of minutes of television to commercial is 35:7.8
3 hours and 50 minutes is 230 minutes
230:X
35:7.8
Multiply both sides by 6.6
X=51.5 minutes
There is about 51.5 minutes of commercials
