I’m stuck... any one able to help?
X^4 + 5x^3 + 3x/x

Step-by-step explanation:

1) divide each term in the numerator by the term in denominator:

(remember when dividing subtract the smaller exponent from larger exponent

for example: say a is the larger exponent, do

x^4/x=x^3

5x^3/x=5x^2

3x^2/x=3x

so

x^3+5x^2+3x

hope this helps!

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

5y
