A portion of the Quadratic Formula proof is shown. Fill in the missing statement. Statements Reasons x squared plus b over a tim

es x plus the quantity b over 2 times a squared equals negative 4 times a times c all over 4 times a squared plus b squared over 4 a squared Find a common denominator on the right side of the equation x squared plus b over a times x plus the quantity b over 2 times a squared equals b squared minus 4 times a times c all over 4 times a squared Add the fractions together on the right side of the equation the quantity x plus b over 2 times a squared equals b squared minus 4 times a times c all over 4 times a squared Rewrite the perfect square trinomial on the left side of the equation as a binomial squared ? Take the square root of both sides of the equation x plus b over 2 times a equals plus or minus the square root of the quantity b squared minus 4 times a times c end quantity, all over 4 times a squared x plus b over 2 times a all squared equals plus or minus b squared minus 4 times a times c, all over 4 times a squared all squared the square root of x plus b over 2 times a equals plus or minus the square root of b squared minus 4 times a times c, all over 4 times a squared x plus b over 2 times a equals plus or minus the square root of b squared minus 4 times a times c, all over 4 times a squared

A garden that is 24 ft by 14 ft has a walkway that is 4 ft wide around it. What is the amount of fencing needed to surround the
SCORPION-xisa [38]
The garden is 24 ft by 14 ft
The walkway stretches all the way around the garden
The walkway is 4 ft wide

Perimeter is found by adding the length of the four sides so this would be 24 + 14 + 24 + 14 = 76
24 + 24 = 48
14 + 14 = 28
48 + 28 = 76

I don't know for sure but I think the length would be 34 using the length formula
p / 2 - w
so 76 / 2 - 4
38 - 4
34

I have no clue though. A picture would make it easier

Jasmine has a bag which contains a nickel, a penny, and a dime. Find the probability of getting a nickel first and then a penny
stepan [7]

Answer:

0.166 = 16%

Step-by-step explanation:

There are three different options to pick in the bag, so the probability of getting a nickel first is 1/3, and then the probability of getting a penny without replacing the nickel is 1/2, as there will be only 2 options remaining after the nickel was picked.

So the final probability is the product of these probabilities:

P = (1/3) * (1/2) = 1/6 = 0.166 = 16%
