Answer:
s=4.75
Step-by-step explanation:
Just substitute the given variable values into the original equation
s=10•½+½•-2•½²
s=5+-1•¼
s=5+-¼
s=-4.75
Answer:
circumference=2×3.142×radius
radius=16.8÷2=8.4
so,
circumference=52.7856cm

Answer:
a). x < 6 or x ≥ -3
b). -3 ≤ x < 6
Step-by-step explanation:
a). Inequality 1,
(x + 4) < (2×5)
x < 10 - 4
x < 6
Inequality (2),
-2(x - 4) ≤ 14
-2x + 8 ≤ 14
-2x ≤ 14 - 8
-2x ≤ 6
2x ≥ -6
x ≥ -3
So the compound inequality will be,
x < 6 or x ≥ -3
(b). Solution set of the given inequality will be,
-3 ≤ x < 6
