Answer:
x^3 -14x^2 -6
Step-by-step explanation:
Your expression is the difference of two polynomials. The parentheses can be removed by using the distributive property. The minus sign outside the second set of parentheses applies to each term inside parentheses.
-5x^2 +3 +x^3 -9x^2 -9
Now, you can group like terms. In "standard form", the degrees of the terms decrease from left to right.
x^3 +(-5x^2 -9x^2) +(3 -9)
And combine like terms.
x^3 -14x^2 -6 . . . . . simplified form of the given expression
Make a comparison
Plug the numbers into the equation aboveh stands for the height of tree


Do cross multiplication
3.5h = 6 × 18
3.5h = 108
h = 108/3.5
h = 30.8571..
to the nearest hundredth
h = 30.86 feet
to the nearest tenth
h = 30.9 feet
