Answer:
(x-18)²+(y+18)²=18².
Step-by-step explanation:
1) the formula is: (x-x₀)²+(y-y₀)²=r², where (x₀;y₀) - coordinates of the centre, r - the length of the radius;
2) according to the formula above:
(x-18)²+(y+18)²=18².
4x2+36x+72
8+36x+72
80+36x
x=20/9
Answer:
2p, since twice as long would hint to multiplication.

Answer:
2 < x < 3
Step-by-step explanation:
Inequalities: <em>4x - 4 < 8 ∩ 9x + 5 > 23</em>
Simplify:
4x - 4 < 8 ∩ 9x + 5 > 23
4x < 12 ∩ 9x > 18
<em> x < 3 ∩ x > 2</em>
Combine inequalities: 2 < x < 3
