By the Intersecting Secants Theorem we have
2x(2x+7)=x(x+23)
4x^2+14x=x^2+23x
3x^2=9x
3x=9
x=3
Since DY is length 2x,
the length of DY is 6.
Answer:
I have to say, I was a bit stumped on this one for some reason, but I believe your answer is y^2.
Step-by-step explanation:
All four variables , (14, 15, y^2, & y^4) should all have a common denominator, but I only see similarities in y^2 with y^4 and 14 with 15, but the y's can be understood ones. Multiply your common variables and get y^2. Could someone check me in that though?
The degree of a polynomial is the highest degree of any term.
The degree of a term is the sum of the exponents of all the variables of the term,. A plain variable has degree 1.
One term is -3x^9.
That has the largest exponent of any term, so the degree is 9.
If p is not the hypothesis of a conditional statement then q is not the conclusion
