The answer is
B) 2n - 5
because it's -5 than twice the width (2n)
Answer:
A. 7 pounds
B. $1.60
Step-by-step explanation:
For A you Divide 21 by 3
For B you Divide 14 by 9
Volume of Cuboid = l x b x h
9000 mL = 30 x 15 x h
h = 9000/30 x 15
h = 20cm
21
is what I got on my calculator
Hello!
x² - 4x + 6 = 9 <=>
<=> x² - 4x + 6 - 9 = 0 <=>
<=> x² - 4x - 3 = 0 <=>
<=> x = -(-4)±√(-4)²-4×1×(-3)/2×1 <=>
<=> x = 4±√16+12/2 <=>
<=> x = 4±√28/2 <=>
<=> x = 4±2√7/2 =>
=> x = 4+2√7/2 and x = 4-2√7/2 =>
=> x = 2+√7 and x = 2-√7
The equation has two solutions.
Good luck! :)
