Calculus Work:
8x^3 + 10x^2 - 15x divided by 2x + 1 in the format of q(x) + r(x)/b(x)

8x³ + 10x² - 15x ÷ 2x + 1 = 8x³ + 10x² - 15/2 + 1 = 8x³ + 10x² - 6 1/2

Step-by-step explanation: let 2:3:5:8 be 2x,3x,5x,8x respectively .

*angles in a quadrilateral is 360 degree

*2x+3x+5x+8x=360

*18x=360

*x=360/18

*x=20

now substitute x in these:

2x=2x20=40

3x=3x20=60

5x=5x20=100

8x=8x20= 160

so these are the following angles: 40,60,100 and 160
