Answer:
f(x) = 16x2 + 32x - 9
To find the "zeros", set f(x) = 0:
0 = 16x2 + 32x - 9
The equation is solvable by factoring or by using the quadratic formula. The factors (use the "ac" method) are:
0 = (4x-1)(4x+9)
x = 1/4 = 0.25 and x = -9/4 = -2.25

<h3><u>
Step-by-step explanation:</u></h3>
- Perimeter: Side 1 + Side 2 + Side 3
- => x + 4 + 3x + 7 + x + 9 = 56
<h3><u>Conclusion:</u></h3>
Therefore, the value of x is 7.2.

The order of the scale drawings from smallest to largest is
Smallest
1 in to 1 ft
Second smallest
1 in to 1 yd
Largest
1 in to 1 m
Given the following scales:
1 in to 1 ft
1 in to 1 m
1 in to 1 yd
We are to arrange the scales from smallest to largest.
Since 1 in is used as the base conversion for all the scales, we can convert the other scales to yards for consistency's sake.
Convert 1m to yards
1m = 1.1yards (From the question)
Convert 1ft to yards. According to conversion factor;
1 feet = 0.333333 yards
Ordering the scales from smallest to largest will give
0.33333yard (1 in to 1 ft), 1 yard (1 in to 1 yd), 1.1yards (1 in to 1 m)
