4 0

Answer:

\bold\purple{Quadratic \:  \: eq {}^{n} = x {}^{2}  - ( \alpha  +  \beta )x +  \alpha  \beta} \\

Sum of roots ,

( \alpha  +  \beta ) = (3 + 9) = 12

Product of roots ,

( \alpha  \beta ) = (3)(9) = 27

Substituting the values in the above equation ,

\bold{x {}^{2}  - ( \alpha  +  \beta )x +  \alpha  \beta}  \\\\ \bold{⇢ x {}^{2}  - (12)x + 27} \\\\ \bold\blue{ ⇢x {}^{2}  - 12x + 27}

hope helpful~

The width of a rectangle is 22 inches and the perimeter is at least 165 inches. what inequality could be used to find the minimu
Lera25 [3.4K]
The answer is D.

We know that a rectangle has two widths that are equal and two lengths that are equal. One width is 22, so the other one is also 22.

If you wanted to find the lengths, you would add both widths together (same as multiplying a width by two) and add that to the two lengths equaled to the perimeter.

So, 22 * 2 + 2x = perimeter of rectangle. We added all four sides together.

We know that the perimeter is at least 165, so 22 * 2 + 2x = 165. Here's the twist. They want the most minimum possible length. So, what answer choice gives you 165 or less for the most minimum or smallest length while still getting to 165?
That is D.
22 * 2 + 2x < = 165.
Hope this helped!

working together two mathletes solve 32 math problems in a certain amount of time how many problems will 3 mathletes solve if th
dexar [7]

If they together at the same rate for the same amount of time, they will solve 48 math problems,

From the question, we can see that two mathletes solve 32 math problems in a certain amount of time, this can be written as:

  • 2 mathletes = 32 math problems

In order to determine the number of problems for 3 mathletes, this is expressed as:

  • 3 mathletes = x

DIvide both expressions:

  • 2/3 = 32/x

Cross multiply

2x = 3* 32

x = 3 * 16

x = 48math problems

Hence if they together at the same rate for the same amount of time, they will solve 48 math problems,
