The required picture is attached below.
Step-by-step explanation:
We need to draw a picture that represents 3 times 50 equals 150.
The given equation is
Steps for representing the given problem in pictorial form:
Step 1 : Take one box which represents 50.
Step 2 : 3 times 50 means addition of 3 boxes of 50 each.
Step 3 : 50 + 50 + 50 =150
Hence 3 times 50 is equals 150.

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.
