Your verbal description of the expression you're dealing with is a bit unclear, but here's what I'm assuming you're given:
To subtract two fractions, you need a common denominator. To find out what that should be, factor the two denominators.
The least common denominator (LCD) must contain each
distinct factor, so the LCD is
Now change the two fractions so they have the LCD. In this case, that means to multiply top & bottom of the first fraction by the "missing" factor (x + 2) and the second fraction's top & bottom by (x - 3).
Now, distribute the 2 in the first numerator and 3x in the second numerator (careful with that subtraction sign!) and simplify.
Can you finish it?
It's 450 because 1 oz= 150 calories so that means 3oz= 450
Answer:
96
Step-by-step explanation:
Total area is 12*8=96 square feet
Each tile is 1 square foot
The required tiles are therefore 96/1=96
V should equal -128 :) Hope this helps you
it is 40.5 because area equals base times height.
