I pretty sure it (B) sorry if I’m wrong
Answer:
24-3x
Now, Putting the value of x=5
= 24-3×5
=24-15
=9
Step-by-step explanation:
#Hope it helps u
A^2+b^2=c^2
20^2+b^2=29^2
400+b^2=841
-400. -400
b^2=√441
b=21
(3x^2+5x-2)- ((2-x^2+2x+5))
(3x^2+5x-2)- ((7-x^2+2x))
Since no more can be added or broken down
3x^2+5x-2 - 7-x^2+2x
2x^2+7x-9
