What is (4x-2)•6(2x+7) in standard form

1 answer:

4 0

  y = 12(2x - 1)(2x + 7)
  y = 12(2x(2x + 7) - 1(2x + 7))
  y =12(2x(2x) + 2x(7) - 1(2x) - 1(7))
  y = 12(4x² + 14x - 2x - 7)
  y = 12(4x² + 12x - 7)
y = 12(4x²) + 12(12x) - 12(7)
y = 48x² + 144x - 84
-48x² - 144x + y = -84
-1(-48x² - 144x + y) = -1(-84)
-1(-48x²) + 1(144x) - 1(y) = 84
48x² + 144x - y = 84

Answer: 1,400 calories

Bianca jogged 1.25 miles per day for 8 days. so 1.25*8 would equal 10 miles.

Since she jogged 10 miles and burned 140 calories per mile, if we multiply 10*140, we would get 1,400.

So last month, she lost 1,400 calories.
