Answer:
The surface area of the figure is 352 cm².
Step-by-step explanation:
Given:
Length(l) = 12 cm.
Width(w) = 4 cm.
Height(h) = 8 cm.
Now, to find the surface area.
By putting the formula to get the surface area:
Surface area = 2(l×w+w×h+h×l)



Therefore, the surface area of the figure is 352 cm².

Answer:
f(x)^-1 = 
Step-by-step explanation:
f(x) = (4x - 3) / 7
y = (4x - 3) / 7
x = (4y - 3) / 7
x / 7 = 4y - 3
x/7 + 3 = 4y
y = 
Answer:
A line parallel to the line y = x -4 would have a slope of 1.
A line perpendicular to the line y = x -4 would have a slope of -1.
Remember, parallel lines are lines that never intersect, which means that they cannot possibly have different slopes. A perpendicular line will <em>always</em> have the opposite slope as the first line, because the two lines must intersect at a 90 degree angle. The attached image shows how this works.
