What is the factorization of the following trinomial?

Mathematics

I must assume that by "15x2 - 44x - 36" you actually meant "<span>15x^2 - 44x - 36."  Use " ^ " to denote exponentiation, please.

One by one, take each of the following sets of possible factors and mult. them out to determine whether the result equals  </span>15x^2 - 44x - 36:
<span>
(5x - 9)(3x + 4)
(3x - 4)(5x + 9)
(5x - 18)(3x + 2)
(5x + 18)(3x - 2)

First one:  use the "foil" method:  (5x)(3x) + 20x - 27x - 36.  This does not simplify to </span>15x^2 - 44x - 36 and so is not the correct choice.  Go on to the second answer choice and continue this check.

the eagle trucking company must deliver 7/8 ton of cement blocks and 5/8 ton of bricks how much will this load weigh?
Mademuasel [1]
This load will weigh 1.5 TONS ALTOGETHER.

So, the truck is delivering a \frac{7}{8} ton of cement blocks, and a \frac{5}{8} of bricks. To find how much this load weighs, we'd have to add the two fractions together, which proves to be quite easy, because the denominators are already the same, so we wouldn't have to change anything.

\frac{7}{8} + \frac{5}{8} = \frac{12}{8}

And now, we would want to convert that fraction into a whole number, or at least a decimal, to find how many tons the truck is carrying. So we would divide. Once the work is done, here is what would happen:

12 ÷ 8 = 1.5

And there's your answer. The truck is carrying 1.5 TONS.
