Answer:
b -17
Step-by-step explanation:
−a^2 − 3b^3 + c^2 + 2b^3 − c^2 =
= -(3²) - 3(2³) + (-3)² + 2(2³) - (-3)²
= -9 - 3(8) + 9 + 2(8) - 9
= -9 - 24 + 9 + 16 - 9
= -17
Answer:

Step-by-step explanation:
Hope this helps!
Answer:
C
Step-by-step explanation:
add the two x^2 parts = 10 x^2
so answer is B or C
add the constants 7 + 6 = 13 so answer C
Answer:
The shortest sides is 3x-10
Step-by-step explanation:
This is because if you do the algebra which is 4x+3+2x+8+3x-10=136, x=15. Now that you have 15 you plug it into each sides x value. First, 4x+3= 4*15+3=63
Second, 2x+8=30+8=38
Lastly, 3x-10=45-10=35
So, as you can see here 35 is the lowest value which means the side (3x-10) is the shortest.
