For a rectangle, the two verticle sides should be congruent (of the same length)
2y+4=10
Subtract 4 from both sides
2y=6
Divide both sides by 2
y=3
Final answer: 3
Answer:
5.7 liters
Step-by-step explanation:
The sum of 2 liters, 5 deciliters of lemon juice and 3 liters, 2 deciliters of water will be given as
2+3=5 liters
5+2=7 deciliters
Therefore, we get 5 liters, 7 deciliters of lemonade
Conversion
10 deciliters equal to 1 liter hence 7 deciliter will be 7/10=0.7 liters
5+0.7=5.7 liters

Answer:
-2, 3, -0.5 + 0.866i, -0.5 - 0.866i.
Step-by-step explanation:
As the last term is -6 , +/- 2 , +/- 3 are possible zeroes.
Try 2:-
(2)^4 - 6(2)^2 - 7(2) - 6 = -28 so 2 is not a zero.
3:-
(3)^4 - 6(3)^2 - 7(3) - 6 = 0 so 3 is a zero.
(-2)^4 - 6(-2)^2 - 7(-2) - 6 = 0 so -2 is also a zero.
Divide the function by (x +2)(x - 3), that is x^2 - x - 6
gives x^2 + x + 1
x^2 + x + 1
So we have x^2 + x + 1 = 0
x = [-1 +/- √(1^1 - 4*1*1)] / 2
= -1 + √(-3) / 2 , - 1 - √(-3) / 2.
= -0.5 + 0.866i, -0.5 - 0.866i
Assuming the number is 331/2, or 331 over 2:
331/2 = 165.5 ÷ 400 = .4138 x 100% = 41.38%
100% - 41.38% = 58.62% not nickels
If the number is 33 1/2, or 33 and one half
33 1/2 = 67.5 ÷ 400 = 0.0838 x 100% = 8.38%
100% - 8.38% = 91.62% not nickels
