Answer:
It's incorrect because the equation is solve incorrectly the anwer is r= -4
Step-by-step explanation:
Add 4r4r to both sides.
-3r+9+4r=5
−3r+9+4r=5
2 Simplify -3r+9+4r−3r+9+4r to r+9r+9.
r+9=5
r+9=5
3 Subtract 99 from both sides.
r=5-9
r=5−9
4 Simplify 5-95−9 to -4−4.
r=-4
r=−4
Answer: 3. 4
4.
Step-by-step explanation:
8^2 + 12^3 = c^2
64 + 144 = c^2
208 = c^2
√208

The final answer is the square root of 208
8^2 + b^2 = 17^2
64 + b^2 = 289
-64 64
b^2 = 225
