Find the surface area of the composite solid.

281 ft²

Step-by-step explanation:

Cuboid + lateral surface area of the pyramid - square base

2[(4×12)+(4×5)+(12×5)] + 4[½×5×(12-7)] - 5²

2(48+20+60) + 4(12.5) - 25

2(128) + 50 - 25

256 + 25

281 ft²

the answer is attached to the picture

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
