Answer:
the first one is -4.6
Step-by-step explanation:
The answer to this question is a equilater triangule
we know that
distributive property of multiplication over addition:

now, we will verify each options
option-A:
3 × (4 + 5) = (3 × 4) + (3 × 5)
We can see that both sides match with property
so, this is TRUE
option-B:
3 × (4 + 5) = (3 + 4) × (3 + 5)
We can see that right side does not match with property
so, this is FALSE
option-C:
3 × (4 + 5) = (3 × 4) + 5
We can see that right side does not match with property
so, this is FALSE
Each "x" on the number line seems to represent a tree that sap has been collected from. That's 15 trees. Furthermore, you know that the total amount of sap is 8 gallons, because it's stated in the question.
To get the amount of sap that would be collected from each tree if it had been distributed equally (also known as the <em>average</em> amount of sap collected from each tree), just do exactly that.
Mathematically, this means you would divide the 8 gallons by 15 trees, or 8 ÷ 15. The total amount of sap collected is equivalent to an average of eight fifteenths of a gallon per tree.
