B. h(x) = 2x^2 - 3x + 3

Step-by-step explanation:

Given

f(x)=3x+5

g(x)=2x^2 - 6x - 2

h(x) is sum of the functions f(x) and g(x)

Thus,

h(x) = f(x) + g(x)

substituting value of f(x) and g(x) as given above we have

h(x) = 3x+5 + 2x^2 - 6x - 2

as ( 3x - 6x = -3x and 5- 2 = 3) , we have

h(x) = 2x^2 -3x + 3

Thus, correct answer is option  B. h(x) = 2x^2 - 3x + 3.

The formula for axis of symmetry is -b/2a.

For f(x):
0/2(4)
0/8
Axis of symmetry= 0

For g(x)
-(-8)/2(1)
8/2
Axis of symmetry= 4

For h(x)
-(-12)/2(-3)
12/-6
Axis of symmetry= -2

Order from least to greatest: -2, 0, 4

Final h(x), f(x), g(x)

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.
