Answer:
Step-by-step explanation:
V=4/3πr^3
288πcm^3=4/3πr^3
288×3πcm^3=4/3πr^3
864πcm^3=4πr^3
r^3=216
r=6cm
A = <span>x^3 + x^2 + x + 1
A = x^2(x +1) + (x+1)
A = (X + 1)(x^2 + 1)
W = x +1
so L = x^2 + 1 because A = L*W
answer
</span><span>A) x^2 + 1 </span>
Answer:
6x+2x
Step-by-step explanation:
Answer:
Đó là một phép toán phải không?
Step-by-step explanation:
Bạn có thể làm được..
Break down the problem into these two equations;
x = -31
-x = -31
Solve for the 1st equation; x = -31
x = -31
Solve for the 2nd equation; -x = -31
x = 31
Collect all solutions
x = ±31
Check the solution
When x = -31, the original equation; |x| = -31 does not hold true. Thus, we will drop x = -31 from the solution set.
Check the solution again;
When x = 31, the original equation |x| = -31 does not hold true as well. Thus we will drop x = 31 from the solution set.
Therefore,
<u>No solution exists to this equation. </u>
