Answer:

\sqrt{(4-a)(4+a)} =b

Step-by-step explanation:

16 = a^2 + b^2

16 - a^2 =b^2

4^2 - a^2 = b^2

\sqrt{4^2 - a^2} =b

\sqrt{(4-a)(4+a)} =b

The least number of possible bags of beads packed would be 2 because the greatest common factor is 2. To find how many of each bead is packed into each bag you would have to divide 14 and 2 which is 7, 16 and 2 which is 8, and 18 and 2 which is 9, so there will be 8 read beads, 9 orange beads, and 7 green beads.


Hope this helps!!!!

Classify the following polynomial function, −3x(x2−4)(2x2+5)based on degree and number of terms.
Free_Kalibri [48]

Answer:

Quintic Trinomial (2nd option)

Step-by-step explanation:

We know that this is a quintic polynomial because the degrees add up to 5. If we expand the polynomial, we have -3x(x^2-4)(2x^2+5)=(-3x^3-12x)(2x^2+5)=-6x^5-45x^3-24x^3-60x=-6x^5-69x^3-60x

So, there are 3 terms, which is a trinomial.

What’s the square root of 13 to the nearest integer
Marianna [84]

Answer:

4

Step-by-step explanation:

First off, integers are Whole Numbers (1,2,3,4, etc), so we are rounding the answer to the nearest whole number.

The square root of lets just say 25 means you are finding a number that multiplied by itself will equal 25 (the answer is 5).

Now for 13, there is no perfect square, however the closest whole number that multiplied by itself to 13 is 4.

4*4= 16

3*3=9

5*5=25

As you can see above 4 is the closest number to 13.

Now, the ACTUAL value of the square root of 13 is 3.60555128, but we are rounding up to the nearest whole number which is 4 :)
