Answer:
x = (-5 ± 2√10) / 3
Step-by-step explanation:
5 − 10x − 3x² = 0
Write in standard form:
-3x² − 10x + 5 = 0
Solve with quadratic formula:
x = [ -b ± √(b² − 4ac) ] / 2a
x = [ -(-10) ± √((-10)² − 4(-3)(5)) ] / 2(-3)
x = [ 10 ± √(100 + 60) ] / -6
x = (10 ± 4√10) / -6
x = (-5 ± 2√10) / 3
Answer:
c) 60,480
Step-by-step explanation:
9×8×7×6×5×4×3×2×1
÷
3×2×1
Cancel same numbers in the numerator and denominator.
So you're going to have= 9×8×7×6×5×4 divided by 1
Which gives you, 60,480.
Hope this helped:) Mark me brainiest please.
