6. area of parallelogram is b x h. the base is 3, the height is 2. the height IS NOT 2.2. THAT IS THE SLANT HEIGHT NOT THE HEIGHT
The easiest way to solve this comparison without any unusual comparisons is to find a common denominator for the two fractions.
2/5 = 18/45
4/9 = 20/45
Since 20/45 is bigger than 18/45, we know that 4/9 is greater than 2/5
Add numbers with the same amount of variables
-x^2 + (-7x^2) = -8x^2
– 28x (+ 14x )= -14x
7 (+ 8) = 15
-18x² - 14x + 15 is your answer
hope this helps
20% because 9 divided by 45 is 0.2 which is 20%
