Beulah used 3/5 pounds of dough, 3/4 pound of sugar, & 2/3 pounds of sprinkles to make donuts. how many pounds of donuts did beulah make? type answer as a mixed-number fraction.

If we want to know the total amount of pounds of donuts, we firstly have to make a sum of each element Beulah used to make her donuts:

where D is the total pounds of donuts made.

In order to solve this, we have to take the Lowest Common Denominator, this means that we have to multiply de denominators to obtain a common denominator, in this case the value is:

this is the common denominator now. Then we have to divide this value by each denominator and then multiply the result with each numerator, as follows:

with the following result:

This is D, the total pounds of donuts made.

Now, we need to express this as a mixed-number, in this case we have to:

having the final result:

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
