Answer:
Step-by-step explanation:
x²-3x-2=0
delta = b² - 4ac a=1 b = -3 c = -2
delta = (-3)² - 4(1)(-2) =17
X1 = (3-√17)/2 ≃ - 0.56
x2 =(3+√17)/2 ≃3.56
152
6840 divided by 45 is 152
idk
X = -5
Y = 0
I think you would divide all of your numbers.
320 CM^3
6 x 8 x 5 =240
.
prism volume = 4 x 4 x 5 = 80
240 + 80 = 320 cm^3
