So, we know that the quadratic formula is x=-b+- the square root of b^2-4ac and all of this divided by 2a. You might be like "wow, where did all of these come from?" It is actually really easy. So, let's take your first equation: 2x^2-19x+24=0. So, let us look at the standard form for a quadratic formula: a^2+b+c=0. Now, If you look at the normal equation and the standard form for a quadratic, you will see that they are alike. Now, just match the letter with the number: a=2, b=-19, and c=24. Now that you know what each letter represents, you can plug everything into the equation x=-b+- the square root of b^2-4ac and all of this divided by 2a.

3 is (x-3)(x-9) as when you use FOIL, you get -12x when adding -3x and -9x and also 27 when you multiply -3 times -9.

Answer:

45 strawberry muffins

Step-by-step explanation:

In order to solve this equation you are going to have to multiply 150 by 1/5 bananas and 1/2 blueberry in order to get how much strawberry muffins were made. So first we are going to convert 1/5 and 1/2 into decimals:

1/5 = 0.2

1/2 = 0.5

Now we are going to multiply 0.2 and 0.5 by 150 in order to figure out how much banana and Blueberry muffins were made:

0.2 * 150 = 30

0.5 * 150 = 75

So 30 banana muffins were made and 75 blueberry muffins were made, now that we know this we are going to add 30 and 75 together and subtract the answer from 150. THe reason we are subtracting 75 + 30 from 150 is because we are trying to segregate the strawberry muffins from the total number:

75 + 30 = 105

now we subtract:

150 - 105 = 45

So the number of strawberry muffins made was 45.

I hope this helps.
