3x^2 - 12 = 0
Personally, I would divide each side by 3 x^2 - 4 = 0
Then I would add 4 to each side x^2 = 4
Then I would take the square root of each side: x = +4
x = -4 .
Having found both solutions, I would relax with a cup of tea.
I typed it in a calculator and got 68,000,000, so just correct me if im wrong.
It should take 2.2 hours, since 5.5 / 2.5 = 2.2.
Find the area do base times height times .5
In this item, we are given that the length of the rectangle is equal to 80% of its width and that its width is equal to 95 inches. The length can be calculated by multiplying the decimal equivalent of the given percentage and the width. That is,
l = 0.8w
If we are to substitute the given value,
l = 0.8(95 inches) = 76 inches
Hence, the answer is that the length is 76 inches.
