Answer:

x=6

Step-by-step explanation:

Since the angles are the same , we can use the angle bisector theorem

3           x

------- = --------

x-4            4

Using cross products

3*4 = x(x-4)

Distriubte

12 = x^2 -4x

Subtract 12 from each side

12-12 = x^2 -4x-12

0 = x^2 -4x-12

Factor

0 = (x-6) (x+2)

Using the zero product property

x-6 = 0   x+2 =0

x=6    x=-2

But x cannot be negative since it is a length

x=6

For this case we have the following polynomials:
 3x2
 x2y + 3xy2 + 1
 We have then:

 For 3x2:
 Classification: polynomial of one variable:
 Degree: 2

 For x2y + 3xy2 + 1:
 Classification: polynomial of two variables
 Degree: 2 + 1 = 3
 Answer:
 
The polynomial 3x2 is of one variable with a degree of 2.
 
The polynomial x2y + 3xy2 + 1 is of two variables a with a degree of 3.

There are 7 boxes stacked on the floor in the math department supply closet. Each box has a height of 10 inches or 8 inches. The
Orlov [11]

Answer:

5 of the 7 boxes are 8 inches in height

Step-by-step explanation:

Mathematically;

1 ft = 12 inches

So, 5 ft will measure 5 * 12 = 60 inches

So from what we have ,

We want to combine 8 and 10 inches to give 60 inches total

Let the number of 10 inches be x and the number of 8 inches be y

Mathematically;

x + y = 7 •••••(i)

10x + 8y = 60 ••••(ii)

From equation i, x = 7-y

Put this in equation ii

10(7-y) + 8y = 60

70-10y + 8y = 60

70-60 = 10y-8y

2y = 10

y = 10/2

y = 5
