Answer:
2.2 hr
Step-by-step explanation:
Let t = time

105t = distance of eastbound train
95t + 105t = 440
200t = 440
t = 2.2 hr.
Answer:
4a^2 + 12ab + 9b^2.
Step-by-step explanation:
Use the identity (a + b)(a + b) = a^2 + 2ab + b^2 :
So
(2a + 3b)(2a + 3b)
= (2a)^2 + 2*(2a)(3b) + (3b)^2
= 4a^2 + 12ab + 9b^2.
Answer:
I think it 1 but I may be wrong
Step-by-step explanation:
Add the one from the left to the 63 to get 64. Then divide both sides by 4 and get x^2=16. Take the square root of both sides to get x to equal 4.
