Answer:

The answer is 2 and (-9)

Step-by-step explanation:

x² + 7x – 18 = 0

x² + 9x – 2x – 18 = 0

x(x + 9) – 2(x + 9) = 0

(x – 2) (x + 9) = 0

x = (2, -9)

Thus, The zeroes of the polynomial is 2 and (-9).

Solve: −3(5+8x)−20≤−11

Tatiana [17]

-3(5 + 8x) - 20 ≤ -11 |use distributive property: a(b + c) = ab + ac

-15 - 24x - 20 ≤ -11

-35 - 24x ≤ -11 |add 35 to both sides

-24x ≤ 24 |change signs

24x ≥ -24 |divide both sides by 24

x ≥ -1
