Suppose that maura continues to drive at her increased speed write an equation that represents the additional distance ,d ,in miles that maura will travel if she drives at that speed for x hours

Well for this equation if your trying to find the distances (d)
You need to know the speed (S) and the amount of hours (T)  she traveled

So your equation would look like this d= S* T

Letter c so sorry if i’m wrong ):

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
