Answer:
12x^2-25x-7
Step-by-step explanation:
Multiply each term by its counterpart in the parenthesis.
4x*3x and 4x*-7
1*3x and 1*-7
This gives you 12x^2-4x*7+3x-7 when the like terms are combined.
Collect the like terms, which will give you 12x^2-25x-7

Step-by-step explanation:
Just took the test
Answer:
v = s/t
v = (381.59 miles) / (5.5 hours)
v = 69.38 mph
In this problem you use cosine because you know the hypotenuse and you want to know the adjacent side of the triangle. So in your calculator you would input cos(52). Then you would multiply that answer with the hypotenuse side. So your equation would be this: cos(52) x 13
The answer is B. CD=KL, DE=LM, EF=MN, and so on
