1. Find the Greatest Common Factor (GCF)
GCF = 2
2. Factor out the GCF (Write the GCF first)
2(14a/2 + 8/2)
3. Simplify each term in parentheses
2(7a + 4)
The last answer Is wrong it should have a negative slope
If 2a = -10, that means a = -5 Because 2(-5) makes -10.
Thus, -6(-5) = 30 #
Therefore, -6a = 30
Answer:
A - 4? (Don’t quote me)
Explanation:
It says the tank needs to be quadrupled, and quadrupled means by 4.
Let 'x' be the distance from THE far bank where 700 is the distance to the NEAR bank
boat one has travelled 700 (rate = 700/unit time) boat two has travelled x rate = x / unit time
boat one then travels x + 400 more and boat two travels 700 + (700+x -400) more when they meet
The time is the same rate x time = distance distance/rate = time equate the distances divided by the respective rates
(700 + x + 400)/700 = ( x + 700 + (700+x-400) )/x
1100x + x^2 = 1400x + 700000
x^2-300x -700000 = 0 quadratic formula yields x = 1000
One boat travels 700 the other 1000 whe they first meet.....width of river = 700+ 1000 = 1700 m
