1st strategy: Add the first two terms and the last two.
16+35 + 24+14
51 + 38 = 89
2nd strategy: add the first and last term and the middle 2 terms.
16 + 35 + 24 + 14
30 + 59 = 89

Answer:
The answer in the attached figure
Step-by-step explanation:
step 1
Find the area of one blue square
step 2
Find the area of one orange triangle
Part 1) 
Divide the total area by the area of one orange triangle
Part 2) 
Divide the total area by the area of one blue square
Part 3) 
Let
x----> the number of blue squares
y ------> the number of orange triangles
we know that
Construct a table and prove different values for x and for y
we have
x=2, y=3
Two blue squares and three orange triangles
Area of blue squares
Area of an orange triangles
so
the area total is
Answer:
3. positive correlation but not causal relationship
Step-by-step explanation:
A positive correlation is when one factor increases, the other factor increases as well.
A negative correlation is when one factor increases, the other factor decreases.
A causal relationship is when one factor <em>causes </em>the other factor change in a certain way (i.e. increase or decrease).
More people buy ice cream as the day becomes hotter and sunnier. This also applies to people choosing to wear sunglasses. Therefore, there is a positive correlation between the two (because both increase). However, this is not a causal relationship because the cause of both is the hotter and sunnier day.
