Answer:
3(r + 5)(r - 5)
Step-by-step explanation:
Both 3 and 75 are divisible by 3, so we take out a 3.
3(r^2 - 25)
Next, we can factor r^2 - 25. It's a difference of squares.
3(r + 5)(r - 5)
Brainliest, please :)
It is 395.3 use calculators or do the division out of paper
I think its ummm uhhh mmmm uhhhh
The awnser is would be 42,40,58
Yanira = Y
Tim = T
Hannah = H
-----------------
Therefore:
Y=T+3
Y=2H
T=H+2
---------------
Now, we know that:
Y=T+3
But we also know that:
T=H+2
Therefore:
Y=(H+2)+3
Y=H+5
-------------------
Now we can combine the equations:
Y=H+5
Y=2H
Therefore:
2H=H+5
2H-H=5
So, H=5.
---------------------
If H=5,
Y=2H=2*5=10
---------------------
If H=5,
T=H+2=5+2=7
-----------------------
