Answer:
![56x^{2}+3x-20](https://tex.z-dn.net/?f=56x%5E%7B2%7D%2B3x-20)
Step-by-step explanation:
You can use the FOIL (first, outer, inner, last) to find the answer.
(7x - 4) · (8x + 5) = (7x · 8x) + (7x · 5) + (-4 · 8x) + (-4 * 5)
= ![56x^{2}+35x-32x-20](https://tex.z-dn.net/?f=56x%5E%7B2%7D%2B35x-32x-20)
= ![56x^{2}+3x-20](https://tex.z-dn.net/?f=56x%5E%7B2%7D%2B3x-20)

Step-by-step explanation:
an = a1 + (n - 1).r
r = a2 - a1
r = -4 - (-1)
r = -4 + 1
r = -3
an = a1 + (n - 1).(-3)
an = -1 + (n - 1).(-3)
an = -1 + (-3n + 3)
an = -1 - 3n + 3
an = 2 - 3n
