Answer:
p = -14
Step-by-step explanation:
5/7p - 2/7p + 12 = 6
Combine like terms
3/7 p +12 = 6
Subtract 12 from each side
3/7p + 12-12 = 6-12
3/7p = -6
Multiply each side by 7/3
7/3 * 3/7p = -6*7/3
p = -14

Answer:
20x² - 10x - 30
Step-by-step explanation:
Height = 5
Width = 4x² - 2x - 6
Area of rectangle = length × breadth
Area of triangle = height × width
Area = 5 × (4x² - 2x - 6)
Area = 20x² - 10x - 30
Area of the rectangle is 20x² - 10x - 30
