Answer:
Step-by-step explanation:
x² + 9x+8 = (x+1)(x+8)
Answer:
one solution
Step-by-step explanation:
it has one solution because the slopes of the two equations(1x & 2x) are different, which means the lines of the two equations are not parallel, they have an intersection point(also means one solution).
Answer:
The answer is 1/22.
Step-by-step explanation:
→ (1/8) ÷ (11/4)
→ (1/8) × (4/11)
→ (1×4)/(8×11)
→ 4/88
→ 1/22 [Simplest form]
Thus, 1/22 is the solution.
