Step-by-step explanation:
I know bc i did this before
<h2>♪Answer :</h2>
»(4x - 2y)(3x + 5y)
»4x(3x + 5y) + (-2y)(3x + 5y)
»12x² + 15xy - 6xy - 10y²
»12x² + 9xy - 10y²
so, ABC is :
9514 1404 393
Answer:
yes, yes, no; No
Step-by-step explanation:
We have to assume you have no trouble with single-digit addition and comparison of two numbers.
3+4 > 1 ⇒ 7 > 1 . . . . yes
4+1 > 3 ⇒ 5 > 3 . . . . yes
3+1 > 4 ⇒ 4 > 4 . . . . no
These lengths will not make a triangle because the triangle inequality is <em>not satisfied</em>.
_____
<em>Additional comment</em>
You will notice that we found the result of interest when we added the two smallest numbers (1 and 3) and compared the sum to the largest number (4). This is a shortcut you can use for any "will these make a triangle" question. You don't need to bother comparing larger numbers to smaller ones. You already know they are larger.
I’m not sure but this is what I would do
Runner A (unit rate / constant of proportionality):
54 feet divided by 4.5 seconds = 12 feet per second
Runner B (unit rate / constant of proportionality): 300 feet divided by 20 seconds (It looks like the end point of the line lands between 300 feet and 20 seconds) = 15 feet per second
Unit Rate:
Runner A = 12 feet per second
Runner B = 15 feet per second
Faster Runner:
Runner B is the faster runner as he can run a further distance than Runner A in one second.
