Distribute.
(a + 8)(a -3)
FOIL:
First, Outside, Inside, and Last
a * a = a^2
a * 3 = 3a
8 * a = 8a
8 * -3 = - 24
a^2 + 11a - 24
Distributed Expression: a^2 + 11a - 24
Answer:
infinite number of solutions
Step-by-step explanation:
Work with the second equation. Subtract 8x from both sides.
- 4y + 8x - 8x = -8x - 12 Collect like terms.
-4y = - 8x - 12 Divide by - 4
-4y/-4 = - 8x/-4 - 12/-4
y = 2x + 3
That is exactly the same line as the first given. There is an infinite number of solutions.
