The group of answers that satisfy an equation?  solutions

A single number or variable, or numbers and variables multiplied together? monomial

Produces a graph that is a straight line? linear equation

Something that relates inputs to outputs? function

A way to name a function identifying its input?  domain (not sure if correct)

Step-by-step explanation:

This is how you would proceed:

Centered at D, draw an arc of 7m (3.5cm) within the garden (rectangle).

Centered at B, draw an arc of 4m (2cm) within the garden.

There will be two intersection points, one is outside the garden (that you will not see), and the other is within the garden, which is where the tree should be planted.

See illustration attached.
