Answer:
1) x < 1, x > 9
2) 2 < x ≤ 6, -4 ≤ x < 0
Step-by-step explanation:
1) lx - 5l > 4
x - 5 = 4
x = 9
-(x - 5) = 4
x = -4 + 5 = 1
x < 1, x > 9
3) 1 < lx-1l ≤ 5
1 < x-1 ≤ 5
2 < x ≤ 6
1 < -(x-1) ≤ 5
-5 ≤ x-1 < -1
-4 ≤ x < 0
Answer:
Step-by-step explanation:
It is simply the sumation of a triangle and a rectangle minus a half circle.
area triangle + area rectangle - area half circle = Total area
1/2( bh ) + bh - (π (d/2)²) / 2 = Total area
0.5(7)(6) + (10)(7) - (π (7/2)² ) / 2 = Total area cm²
21 + 70 - 19.24 = 71.76 cm²
