-4x + 3(2x - 5) = 31 (use distributive property to remove parentheses)
-4x + 6x - 15 = 31 (combine like terms)
2x - 15 = 31 (add 15 to both sides)
+15 +15
2x = 46 (divide both sides by 2)
x = 23
Answer:
1. 60 cm^2
2. 132.67 cm^2
3. 72.67 cm^2
Step-by-step explanation:
1. Area of rectangle
A = LW = 5 cm * 12 cm = 60 cm^2
2. Area of circle
A = (pi)r^2 = 3.14(6.5 cm)^2 = 132.67 cm^2
3. Area of shaded region
A = area of circle - area of rectangle
A = 132.7 cm^2 - 60 cm^2 = 72.67 cm^2

Answer:
-3 and -2
Step-by-step explanation:
7x² + 19x + 21 = 4x² + 4x + 3
combine like terms:
3x² + 15x + 18 = 0
3(x² + 5x + 6) = 0
(x + 3)(x + 2) = 0
x = -3
x = -2
