Answer:

Step-by-step explanation:

area of triangular endface = ½×6×8 = 24 cm²

area of rectangular endface = 4×8 = 32 cm²

area of each endface = 24+32 = 56 cm²

area of each 3×10 face = 30 cm²

area of 3×4 face = 12 cm²

area of base = 8×3 = 24 cm²

surface area = 2×56 + 2×30 + 12 + 24 = 208 cm²

PLS HELP QUICKKKKK! Tap the photo to see the full problem. Answer all 3 questions please and I'll give brainliest if it is right
Ghella [55]
3x + 8 = 3x + []

Subtract 3x from both sides.

[] = 8

If you want no values of x, it can be any positive value other than 8.
If you want all values of x, the value must be 8.
If you want only one value of x, it is impossible because both equations have the same slope.
