y2 + 8y + 16 = y2 + 4y + 4y + 16 = y(y + 4) + 4(y + 4) = (y + 4)(y + 4) or (y + 4)2
y=-x+4
She will be 24.S=16 (Sarah is 16 years old)S=4B (Sarah is 4 times as old as her brother)S/4=B16/4=BB=4 (Sarah's brother is 4 years old)How old will Sarah be when she is twice as old as her brother?S+Y=2(B+Y); S= Sarah's age, B= Sarah's Brother's age, Y=years passed16+Y=2(4+Y)16+Y=8+2Y16=8+2Y-Y16=8+Y16-8=Y8=Y (Sarah will be twice as old as her brother after 8 years pass)How old is Sarah after 8 years pass?S+Y=Final Answer16+8=24Checking work:B+Y=4+8=12Is 12 half of 24? Yes.Therefore Sarah will be twice her brothers age when she is 24 and her brother will be 12.-------------------The keys here areSarah's age S = 16Sarah's brother's age B = 16/4 = 4Years that pass = TThe equation isSarah's future age is twice her brother's future age16+T = 2 (4+T)16+T = 8 +2T16 = 8+2T - T16 = 8 + T8 = TSarah's future age = 16 + T = 24
