5x-7
If the first side is just x, then the second side must be 2x-5, or 5 less than twice the first. If this is the second side, then the third must be 2x-2, because the third side "measures 3 more than the second side."
The perimeter is 5x-7 = (x) + (2x-5) + (2x-2).
Answer:
you have it correct, permutation
Step-by-step explanation:
Answer:
![\frac{49}{28}](https://tex.z-dn.net/?f=%5Cfrac%7B49%7D%7B28%7D)
Step-by-step explanation:
Evaluate g(- 4) and f(- 4) by substituting x = - 4 into g(x) and f(x), that is
f(- 4) = - 10(- 4) + 9 = 40 + 9 = 49
g(- 4) = (- 4)² + 12 = 16 + 12 = 28
Then
=
= ![\frac{7}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B4%7D)
Now,
b + 40° = 90° ( right angle )
or, b = 90° - 40°
◆ b = 50°
B) 50°
This is Right answer...
I hope it's help you...
Thanks♥♥
Easy dude.
This simplifies to 4+b
