All sides are the same, hence, all three angles are the same, and each one of them is 60 degrees. Due to that:

7x + 4 = 60

7x = 56

x = 56/7 = 8

8y + 12 = 60

8y = 48

y = 48/8 = 6

Find an equation of the line through (2,7) and parallel to y=3x-6 Y=
Sliva [168]

As we know the formula to calculate the line of equation is y - y1 = m (x - x1)

Where m is the slope. y1 is the first y co ordinate. x1 is the first x co ordinate.

Now we do know that the slope of parallel line is the same as the slope of the original line.

So parallel line slope is 3 so slope for our line is 3. Hence equation is y - 7 = 3 (x - 2) which becomes y = 3x + 1.

Is 4/7 greater or less than 3/5
baherus [9]
No, it is not.

4/7 ≈ 0.5714

3/5 = 0.6

Actually, 3/5 is greater than 4/7.

Another way you could do this is by multiplying 4/7 with 5/5 and by multiplying 3/5 with 7/7.

4/7 * 5/5 = 20/35

3/5 * 7/7 = 21/35

Have an awesome day! :)

Georgia [21]
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.
