Answer:
k = 10
Step-by-step explanation:
Difference means subtract.
2k - 8 = 12
is how that statement is translated.
Add 8 to both sides.
2k - 8 + 8 = 12 + 8
2k = 20
Divide by 2
2k/2 = 20/2
k = 10
Answer:
6 ft^2
Step-by-step explanation:
If the object in question is a cube, then we could say the length is 1, the depth is 1 and the height is 1, in which case each side of the cube has an area of 1 ft^2.
There are 6 such sides, so the total surface area is 6 ft^2.
Next time please be explicit in naming the shape, either verbally or with a diagram.
84.15-1.8*8
Order of Operations says to add and subtract before you multiply, so simplify the expression to: 82.35*8, which is 658.8
