So the answer is choice D. You can check this by differentiating the right hand side and you'll get x^3 back again.
This answer can be found by using the power rule for integrals. That rule is
Answer:
60
Step-by-step explanation:
The perimeter is the measurement around an object.
So first you multiply the 20 and the 10 by 2.
20 * 2 = 40
10 * 2 = 20
Then, add then up!
40 + 20 = 60
Answer: 19 cm
<u>Step-by-step explanation:</u>

99 = 
99 = 
198 = (2x + 13)(x - 4)
198 = 2x² + 5x - 52
0 = 2x² + 5x - 250
0 = 2x²- 20x + 25x - 250
0 = 2x(x - 10) + 25( x - 10)
0 = (2x + 25)(x - 10)
0 = 2x + 25 or 0 = x - 10
= x or x = 10
Since length cannot be negative,
can be disregarded
Larger base: x + 9 = 10 + 9 = 19
