Answer: 2a - 14 = 2(a - 7)
Step-by-step explanation:
Because 2•a = 2a and 2•-7= -4 therefore, the answer is 2(a - 7).
Factor by groupins
x^2 + xy - 2x - 2y
= x(x + y) - 2(x + y)
= (x - 2(x + y)
It should be 15. 88 minus 28 is 60. Then 60 divided by 4 is 15.
Answer:
x^4 + 5x^3 - 12x^2 + 5x + 1
Answer:
5 meters per second
Step-by-step explanation:
First you must find the slope of the graph. Take the rise/run of the function. The graph starts at 8500 meters and goes down to 7500 meters in 200 seconds. the difference between the change in meters is 1000 meters and the change in seconds is 200 seconds. That is 1000/200. This can be simplified to 5/1 which is 5 meters per second.
