You have to find the difference in height between both checkpoints. To do this just calculate 196 - 52. Checkpoint 5 is 144 (meters?) higher than Checkpoint 2.
Subtract 33 from both sides
6x>3x+30-36x>3x+30−3
Simplify 3x+30-33x+30−3 to 3x+273x+27
6x>3x+276x>3x+27
Subtract 3x3x from both sides
6x-3x>276x−3x>27
Simplify 6x-3x6x−3x to 3x3x
3x>273x>27
Divide both sides by 3
3x>\frac{27}{3}x>
3x> 27
Simplify \frac{27}{3}

what table can u put a pic on ur question?
Answer:
y=-93
Step-by-step explanation:
You just substitute 10 for x
y=-7(10)-23
y=-70-23
y=-93
Answer:
(4x -5)(16x^2 +20x +25)
Step-by-step explanation:
The factoring of the difference of cubes is something you might want to memorize, or keep handy:
(a³ -b³) = (a -b)(a² +ab +b²)
Here, the minus sign in the middle tells you this is a difference. The power of x is a clue that this might be the difference of cubes. Your knowledge of cubes of small integers tells you ...
so you can recognize this as ...
(4x)³ - 5³ . . . . . the difference of cubes.
___
Since you are familiar with the factorization above, you can easily write down the factoring of this expression using a=4x, b=5.
(4x -5)(16x² +20x +25)
_____
For "completeness", here is the factorization of the <em>sum of cubes</em>:
a³ +b³ = (a +b)(a² -ab +b²)
Note the linear factor (a +b) has the same sign as the sign between the cubes. The sign of the middle 2nd-degree term (ab) is opposite that.
