Answer:
x³ + 5x + c
Step-by-step explanation:
Using the power rule
∫ a dx =
Thus
∫ x² + 5 dx
= x³ + 5x + c ← c is the constant of integration
x=-2
3x-1=8x+8+1
3x-1 = 8x+9
3x-1+1=8x+9+1
3x= 8x+10
3x-8x=8x+10-8x
-5x=10
-5x ÷-5
10 ÷-5

2x+3+x=18
2x+x= 3x
3x+3=18
18 - 3 = 15
3x = 15
x = 3
b. 0.50x+15=25
so the answer is 20
