The missing reason is (d) Add the fractions together on the right side of the equation

<h3>How to complete the missing reason?</h3>

From the statements, we have the following equation:

x^2 + b/a x + (b/2a)^2 = -4ac/4a^2 + b^2/4a^2

Next, we add the fractions on the right-hand side of the equation.

This gives

x^2 + b/a x + (b/2a)^2 = [-4ac + b^2]/4a^2

The above means that the last statement is gotten by adding the fractions on the right-hand side of the equation.

Hence, the missing reason is (d) Add the fractions together on the right side of the equation

Lulu found a recipe for her favourite snack: yogurt covered peanut clusters. Lulu wanted to make a large batch of peanut cluster

Answer:

How much would it cost to buy 10 pounds of peanuts?

Answer: $35

What is the cost per pound?

Answer: $3.50

Step-by-step explanation:

So first, to find the anser to the first question, we need to find out the second question. So, what is the cost per pound.

Well if she got 4 pounds for $14, we should try dividing 14 by 4.

14 divided by 4 = 3.5 ($3.50)

So the cost per pound is $3.50

Now to find out how much it costs if Lulu bought 10 pounds, we need to multiply.

10 x 3.5 = 35

So if she bought 10 pounds, she would play $35

Aaaaa PLEASE HELPPPPP

There are 20 cups and each one holds 10 fluid ounces. Assuming that she wants to fill them all up to the brim and use the complete 10 fluid ounces for each cup this means she would have a total of 200 fluid ounces: 20 * 10 = 200

1 gallon = 4 quarts

1 quart = 32 fluid ounces

This means that for every gallon she has 128 fluid ounces: 1 gallon (4 quarts/1gallon)(32 fluid ounces/1 quart) = 128

This means she needs at least 200 fluid ounces and she must buy another gallon to satisfy this; 128 * 2 = 256 fluid ounces.

She needs to buy 2 gallons but will have an extra 56 fluid ounces

Please help meeee!!!!!!!!

Answer:

$840$

Step-by-step explanation:

This is a good example of permutations. For the first slot on his shelf, Dylan has 7 trophies to choose from. Then 6, 5, and so on. Since he is only fitting 4 trophies on his shelf, we only continue until we have the slots filled. Thus, we have $7\cdot 6 \cdot 5\cdot 4=\boxed{840\:\text{ways}}$ to do so.

*Note: We do not divide by $4!$ because in this case, order matters. A different order of the same four books still produces different arrangements, so the order matters.

Hello! Please fill in all the blanks:

Vika [28.1K]

Answer:

The distance between of the AM = BM = AB/2 is 3 cm, NC = ND = DC is 3 cm, MN = MB + DC + NC, and MN is 6.

1. AM = BM = AB/2 = 3 cm.

2. NC = ND = DC = 3 cm.

3. MN = MB + DC + NC.

4. MN = MB + DC + NC = 3 + 6 + 3 = 12 cm.

Step-by-step explanation:

Using coordinate geometry, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

Then we know

AM=MB

NC=ND

Then we have

AM+MB=AB

AM+AM=6

Similarly, we have

NC = ND = 3 cm

AM = MB = 3 cm
