36 is the basis of the equation. It is the 100% 7 is the increase in height (inches). It is the 19.44% 43 is the total height. It is 119.44% height of the tree.
Whatever height the tree grow to, if the question is percentage since it was planted, then 36 inches is the basis.
If the problem refers to the height increase based on the latest height measurement, then 43 inches is the basis.
If the 7 inches increase in height is constant every year. Then, an equation will show:
y = 36 + 7x where y is the total growth through the years. 36 is the initial height, 7 is the constant rate of growth, and x is the number of years the tree has grown.
Here are a few pieces of advice that will help you and your math skills:
Take notes. Taking notes during your math classes will help you remember key points and formulas. If you were to ever forget, for example, the quadratic formula, by writing it down you can always reference back to your notes for the quadratic formula.
Practice! Nobody gets everything right the first time. By practicing and doing the math over and over, you will improve your skills and will better remember them.
Ask! Don't be afraid to ask for help. Brainly is designed to help people on certain questions and subjects that they struggle with, including math. So you can always ask us. You can ask your teachers, your peers, and your family as well.
