Answer:
D
Step-by-step explanation:
Given
x³ + 2x² + 7x + 14 ( factor the first/second and third/fourth terms )
= x²(x + 2) + 7(x + 2) ← factor out (x + 2) from each term
= (x² + 7)(x + 2) → D
Answer:
y=x+1
Step-by-step explanation:
The slop and y-int are 1, just like on the graph
Answer:
5.5 hours
Step-by-step explanation:
Given that :
Speed of A = 60 kmphr
Speed of B = 80 kmphr
After what time will distance = 770 km
Speed * Time = Distance
Let time = x
Distance A + Distance B = 770
(60 * x) + (80 * x) = 770
60x + 80x = 770
140x = 770
x = 770 / 140
x = 5.5 hours
