Answer:
true for all real numbers
Step-by-step explanation:
Subtracting z from both sides gives ...
9 ≤ 19
This statement is true for all values of z. The solution is "all real numbers."
Let’s say Joe earned = x, and Marty earned y
Together they earned $210
So, x + y = $210
If Joe earned 3 times as much as Marty then:
x = 3y
Thus we can substitute and say,
3y + y = 210
4y = 210
y = 52.5
x = 3y = 3(52.5)
x = 157.5
Joe earned $157.5 and Marty earned $52.5
The first triangle has a perimeter of 4+6+10 = 20.
The 2nd longest side is 6/20 = 3/10 of the perimeter. In the larger triangle, the 2nd longest side will have length (3/10)*60 = 18.
_____
These side lengths mean the "triangle" is a line segment. That is, it has zero area.

Hey there!☺
We will need to factor . In order to that, we will have to start grouping.
Hope this helps!
