Step-by-step explanation:
Let's write this out as an equation. Let the unknown quantity be x:

Answer:
2 real solutions
Step-by-step explanation:
Remember this messy thing?

The <em>quadratic formula</em>, as it's called, gives us the roots to any quadratic equation in standard form (ax² + bx + c = 0). The information on the <em>type</em> of roots is contained entirely in that bit under the square root symbol (b² - 4ac), called the <em>discriminant</em>. If it's non-negative, we'll have <em>real</em> roots, if it's negative, we'll have <em>complex roots</em>.
For our equation, we have a discrimant of (-3)² - 4(6)(-4) = 9 + 96 = 105, which is non-negative, so we'll have real solutions, and since quadratics are degree 2, we'll have exactly 2 real solutions.

Answer: choice B) counterclockwise rotation of 90 degrees around the origin</h3>
To go from figure Q to figure Q', we rotate one of two ways
* 270 degrees clockwise
* 90 degrees counterclockwise
Since "270 clockwise" isn't listed, this means "90 counterclockwise" is the only possibility.
Well, first you should make both sides of the equation to the power of 2.
So, you'll have 7X = 1225, and then X is 175 :)
Have a wonderful day!
Answer: X - 6
If you were to write an equation you can use Y to represent Joshua's age, X - 6 = Y
