Answer:
F (x) = -3x+5x^2+8 has complex roots.
Step-by-step explanation:
number of roots?
ok.
f(x) = 5xx - 3x + 8 = 5xx + 5x - 8x + 8 ( I was guessing what numbers would sum to -3)
nope.
ok try discriminant: (-3)^2 - 4*5 * 8 = 9 - 160 < 0
2 complex roots
2x-3=7
2x=7+3
2x=10
x=10:2
x=5
Have a nice day!! ^^
B. 196m3 because
Volume = area of cross section x length
Answer:
5 7/15 = D
Step-by-step explanation:
Find a common denominator multiply the many times you did to the denominator to the numerator then subtract.
15 is your common denominator so I would multiply 5 to 2 to get 9 10/15 then I would multiply 3 to 1 to get 4 3/15
Answer:
70
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles
x = 30+40
x = 70
