5 -2 = 3 . . . . . true
Answer:
72
Step-by-step explanation:
Given that 2x + 3y = 12 , then
(2x + 3y)² = 12² = 144 ← distribute left side using FOIL
4x² + 12xy + 9y² = 144 ( subtract 12xy from both sides )
4x² + 9y² = 144 - 12xy = 144 - 12(6) = 144 - 72 = 72
Answer:
150 feet
Step-by-step explanation:
There are 10 marks between the 1st and 11th mark.
Since each mark represents 5 yards, 10 * 5 = 50 yards
Since 1 yard = 3 feet
50 yards = 50 * 3 = 150 feet
