Solve the quadratic equation.<br> (a + 5)2 +36 = 9
Andrej [43]

Answer:

No solution unless you want to solve for an imaginary number which in that case a=27i-5

Step-by-step explanation:

(a+5)^{2} +36=9

(a+5)^2=-27

a+5=\sqrt{-27}

Here you can stop and say "no solution" since you cannot square root a negative number, but if you want you can still solve for an imaginary number:

a+5=\sqrt{-1} \sqrt{27}

a+5=27i

a=27i-5

alisha [4.7K]

Answer:

Option A is the correct choice.

Step-by-step explanation:  

We have been given the system of linear equations written by Draco. We are asked to find Draco's error.

Let us form a system of equations using our given information.

Let m represent the price of one muffin and b represent the cost of one bagel.

We are told that in one hour a bakery sold five muffins and nine bagels for a total of $25.50. We can represent this information in an equation as:

The next hour the bakery sold three muffins and 12 bagels for a total of $28.50. We can represent this information in an equation as:

Now let us see system of equations written by Draco.

We can see that Draco has set the price of 5 muffins and 9 bagels equal to $28.50, which is the price of 3 muffins and 12 bagels.

Therefore, Draco should have set the first equation equal to 25.50 and the second equation equal to 28.50. The correct choice is option A.
