It would take him 58.2 seconds to fill 14 glasses and it would take him 87.3 seconds to fill 21 glasses
Answer:
Please check the explanation.
Step-by-step explanation:
Given the function
(Round to 1 significant number)
-2a²b + a² + 3ab² - b² + 2(a²b + 2ab)
Simplify the parenthesis first.
-2a²b + a² + 3ab² - b² + 2a²b + 4ab
Now, add like terms.
(-2a²b + 2a²b) + 3ab² + 4ab + a² + b²
Simplify.
3ab² + 4ab + a² + b²
That is the simplest it can be simplified.

Answer:
OP = 43.7
Step-by-step explanation:
since the triangle is similar use these ratios.
LM/OP = LK/ON
9/OP = 7/34
do cross multiplication
OP*7 = 34*9
OP = 306/7
OP = 43.71
OP = 43.7
Answer:
width = 8, length = 42
Step-by-step explanation:
Let x = width, then length = 4x+10.
A = l x w
336 = x(4x+10) put into standard form
4x2 + 10x - 336 = 0 divide by 2
2x2 + 5x - 168 = 0 and solve using the quadratic formula and get
-21/2 and 8, the neg answer will not work, so the width = 8, length = 42
