I have attached all the graphs below. I below you cannot factor these down. You might just have to use the graphs to find the values of x.
Hope I helped :)

The height of the box is:
4 ft.
<h2>
Step-by-step explanation:</h2>
Let "h" denotes the height of the box.
Length of box is denoted by "l"
and breadth or width of box is denoted by "b"
We are given l=18 ft
b=8 ft.
Also we are given surface area of rectangular box= 496 ft²
As we know that the surface area of box is given by:

i.e.

Divide both side by 2.

on dividing both side by 26 we get:

Hence, the height of the box is:
4 ft.
Answer:
x = -1
Step-by-step explanation:
2(x + 3) - 4 = 0
2x + 6 - 4 = 0
2x + 2 = 0
2x = 0 - 2
2x = -2
x = -2 ÷ 2
x = -1
Answer:

Step-by-step explanation:
To find the equation of this circle, we must know the center and the radius.
We can find the radius by dividing the value of the distance formula by 2 (since
):

We can then find the center of the circle by averaging the coordinates:


Then, we substitute these values into the equation of a circle:

Answer:
-12
Step-by-step explanation:
f(x) = -3x^2
Let x = -2
f(-2) = -3( -2)^2
= -3 ( 4)
= -12
