Most dilations in the coordinate plane use the origin, (0,0), as the center of the dilation. The center of the dilation will be indicated within the problem (or within the notation).
I would say the 3rd one
Answer:
4 hours
Step-by-step explanation:
The general formula for distance, rate and time is:
d = rt, where distance is the product of rate multiplied by time
Given that one train is moving at a rate of 70 mph and one is moving at a rate of 62 mph in the opposite direction, the combined distance over time is equal to 528 miles. Using the variable 't' for time:
70t + 62t = 528
Combine like terms: 132t = 528
Divide both sides by 132: 132t/132 = 528/132 or t = 4 hours
The factors of 32 are 1, 2, 4, 8, 16, and 32.
The factors of 20 are 1, 2, 4, 5, 10, and 20.
The common factors of 32 and 20 are 1, 2, and 4.
The greatest one is 4.
32 = 4 x 8
20 = 4 x 5
32 + 20 = (4 x 8) + (4 x 5)
32 + 20 = <em>4 (8 + 5)</em>

and I really need brainliest thanks!
I most certainly have no idea :)
