They equal different things. If you simplify the second equation, it is 15x-4 = 15x-12 because of the 3 outside of the paranthesis. Therefore, the equation is wrong.
Answer:
A
Step-by-step explanation:
-5 represents the rate at which the temperature drops while 54 represents the initial temperature.
Answer:
The total distance that the turtle traveled during the 5 seconds recorded is 
Step-by-step explanation:
To estimate distance traveled of an object moving in a straight line over a period of time, from discrete data on the velocity of the object, we use a Riemann Sum. If we have a table of values

where
, then we can approximate the displacement on the interval
by
.
Therefore the distance traveled of the object over the time interval
can be approximated by

This is the right endpoint approximation.
We are given a table of values for <em>v(t)</em>

Applying the right endpoint approximation formula we get,


The total distance that the turtle traveled during the 5 seconds recorded is 
Answer:
58 units squared
Step-by-step explanation:
**I'm doing the question with the 7 by 3 triangle in the picture, not 777 by 333**
Pythagorean Theorem:
, where c is the length of the hypotenuse.
The given sides are legs, therefore, 

c is also one of the sides of the square. A square's area is one of the sides' lengths squared, so:

Answer:
84t+64s-360
Step-by-step explanation:
Multiply through by a common factor
120×(1/5t+1/3s) + 120(-3+1/5s+1/2t)
(24t+40s) + (-360+24s+60t)
Group like terms
24t+60t+40s+24s-360
84t+64s-360
