Let's call Frank's house F, Derek's one D n Evan's E.
F(5,-4)
E(-3,-4)
D(-3,4)
FE=5-(-3)=5+3=8
ED=4-(-4)=4+4=8
We can see the triangle is a half of a square, so FD is 8(√2)≈11.312
11.312+8=19.312
The answer is C.19.31
If all the sides equal(1.2mi and he’s riding on all sides) then he would have to ride his path 6.25 times because 30 divided by 4.8 is 6.25 if he’s only riding on one side then he would ride his path 25 times because 30 divided by 1.2 is 25
We first have to find the factors of 7 and -3 and see which ones add up to -20.
factors of 7 are 1 and 7 factors of -3 are -1 and 3
7 and 1 -3 and 1
therefore, we get (x - 3) (7x + 1)
we can use the FOIL method to verify the answer.
The answer to this question is 7
Answer:
