Solve x2 − 7x = −13. a) x equals quantity of negative 7 plus or minus i square root of 6 all over 2 b) x equals quantity of negative 7 plus or minus i square root of 3 all over 2 c) x equals quantity of 7 plus or minus i square root of 6 all over 2 d) x equals quantity of 7 plus or minus i square root of 3 all over 2

The correct answer option is B) x equals quantity of negative 7 plus or minus I square root of 3 all over 2.

Step-by-step explanation:

We are given the following quadratic equation:

Taking the constant on the same side as the variable to get:

Since, it cannot be factorized so we will use the quadratic formula:

x =

Substituting in the values of a, b and c in the above formula to get:

x=

x = , x =

Therefore, the correct answer option is B) x equals quantity of negative 7 plus or minus I square root of 3 all over 2.

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
