Answer:
the answer is D or x-1/x^2+3x+2
Step-by-step explanation:
Answer:
x = 10
Step-by-step explanation:
Use CPCTC (Corresponding parts of congruent triangles are congruent).
Set the ratios:
First, simplify. Combine like terms:
Next, cross multiply.
Isolate the variable, x. Divide 6.5 from both sides of the equation:
Check:
Plug in 10 for x (Your answer). Cross multiply, then simplify:
(True).

Using the table, we will see that the function is:
t(l) = 3*l
<h3>
How to write the function?</h3>
Here we only have a table to work with, so we need to use that.
In the table, we can see the pairs:
- t(1) = 3
- t(2) = 6
- t(3) = 9
- t(4) = 12
So, in each new level, we just add 3 more toothpicks. Even more, we can see that the number of toothpicks is 3 times the value of l (the level) for all the cases in the table. So this is a linear function.
From that we can conclude that the function will be:
t(l) = 3*l

Answer:
it will cover 360 miles in 6 hours
Step-by-step explanation:
car travels 180 mile in 3 hour
so, in 1 hour it will travel = 180 / 3 = 60 miles
and then in 6 hours it will travel = 60 × 6 = 360 miles
