Answer:
is the CORRECT equation.
Step-by-step explanation:
The given question is INCOMPLETE.
Javier asks his mother how old a tree in their yard is. His mother says, “The sum of 10 and two-thirds of that tree’s age, in years, is equal to 50.” Javier writes the equation { 10 + 2/3} where a is the tree’s age in years. His equation is not correct. What error did he make?
Now here:
a: The tree’s age in years.
Also, “The sum of 10 and two-thirds of that tree’s age, in years, is equal to 50.”
⇒ 10 + two-thirds of that tree’s age = 50
But in the equation written by Javier, the the third fraction is NOT MULTIPLIED by the age of the tree a in Years.
So, the written equation by Javier is Incorrect.
Now, solving the written correct equation for the value of a, we get:
Hence the correct age of the tree = 60 years
Answer:
See below.
Step-by-step explanation:
If it is a regular polygon then you can look up the formula or break it into shapes you do know the formula.
If it is irregular or a composite figure, break it into regular polygons which do have formulas to find the area. Here is an example:
Example:
Find the area of the composite figure by splitting the figure into two shapes - two rectangles.
One rectangle is 2 x 9 = 18.
The other rectangle is 2 x 4 = 8.
Together the area is 18 + 8 = 26.
