A=1 and the x-coefficient is -14. The value of h is -(-14)/(2*1) = 7.
To find the surface area of the rectangular prism, use the formula:
A=2(wl+hl+hw)
Note that: w = 4, l = 12, h = 3
plug into the equation
A = 2((4)(12) + (3)(12) + (3)(4))
Simplify
A = 2(48 + 36 + 12)
A = 2(96)
Multiply
A = 96 x 2
A = 192
192 m³ is the surface area of the rectangular prism.

Answer:
A) 6 in
Step-by-step explanation:
A circles radius is half the length of the diameter. So to find the radius of a circle if you only know the diameter, divide the diameter by 2.
12 divided by 2 is 6
So the radius of the wheel is 6in
Step-by-step explanation:
y=mx-c
m=gradient
L1: y=3x-2
gradient: 3
L2:
3y-9x+5=0
3y=9x-5
y=3x-5/3
Gradient:3
when gradients of 2 lines are equal, the lines are parallel
