Something that is 6ft tall with an 11ft shadow is the same relation as something that is x ft tall with a 33ft shadow. You can set up a proportion and then cross-multiply to solve for x (which is the height of the tree)
Answer:
y² + y + = (y +
)²
Step-by-step explanation:
In most cases, we can factor a polynomial, or quadratic, by looking at the factors of the last term. In this case, the last term is . When we factor a polynomial, we are looking for two expressions that when multiplied together using FOIL (forward-outside-inside-last) will give us the polynomial. For example: (a + b)(a + b) or (a+ b)².
In order to get y² + y + , we are looking for a 'c' value that will add up to '1' which is our 'b' value (ay² + by + c).
Since
Then, we can use as our factor for both expressions. Putting this together we get: (y +
)(y +
) or (y +
)²
