What are the factors of x2 + 3x – 4? (x + 4) and (x – 4) (x + 3) and (x – 4) (x + 4) and (x – 1) (x + 3) and (x – 1)

(x - 1) (x + 4)

Step-by-step explanation:

Product  = -4

Sum = 3

Factors = -1 , 4

x² + 3x - 4 = x²- 1x  + 4x - 4

                = x(x -1) + 4(x - 1)

                 = (x - 1) (x + 4)

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

you meant circumference well the answer is:

17.27876 miles

area is 23.7583

the radius is 2.75 miles

hope this hmu if needed.
