Hello,
x²-5x-2=0
Δ=5²+4*2=33
==>x= (5-√33)/2 or x=(5+√33)/2
The number line would have an open circle that would be on 5 and the line would go right. the number line should count up.
Sagot:
100 cm
Hakbang-hakbang na paliwanag:
Kung ganoon :
Distansya na sakop ng Ruben = 900 centimetri
Distansya na sakop ng Jamie = 10 metro
Pagko-convert sa centimeter:
100 cm = 1 m
x cm = 10 m
Paggamit ng multiplikasyon ng krus:
x = 100 * 10
x = 1000 cm.
Dahil dito Distansya ni Jamie = 1000 cm
Distansya sa pagitan ng Jamie at Ruben;
1000 cm - 900 cm = 100 cm
