80 I’m sorry if it’s wrong but I’m pretty sure I’m right
X = length of shortest side
Therefore the remaining sides will be x +2 and x + 7
x + x + 2 + x +7 = 45
3x + 9 = 45
3x = 36
x = 12
x + 2 = 14
x + 7 = 19
The sides are 12, 14, and 19 cm. long. Hope this helped!

Answer:
25/2
Step-by-step explanation:
Let's solve your equation step-by-step.
18=3−2x+4(18−8)
Step 1: Simplify both sides of the equation.
18=3−2x+4(18−8)
18=3+−2x+40
18=(−2x)+(3+40)(Combine Like Terms)
18=−2x+43
18=−2x+43
Step 2: Flip the equation.
−2x+43=18
Step 3: Subtract 43 from both sides.
−2x+43−43=18−43
−2x=−25
Step 4: Divide both sides by -2.
−2x
−2
