<span>= 3 m/sec² </span>
If you would like to simplify <span>-4 * (7x - 3y - z) - 6 - (-6) * (9x - z + 2), you can do this using the following steps:
</span>-4 * (7x - 3y - z) - 6 - (-6) * (9x - z + 2<span>) = -4 * 7x + 4 * 3y + 4z - 6 - (-6 * 9x + 6z - 6 * 2) = -28x + 12y + 4z - 6 - (-54x + 6z - 12) = </span>-28x + 12y + 4z - 6 + 54x - 6z + 12 = <span>-28x + 54x + 12y + 4z - 6z + 12 - 6 = 26x + 12y - 2z + 6
</span>
The correct result would be <span>26x + 12y - 2z + 6.</span>
Answer:
112 in.³
Step-by-step explanation:
This box is a combination of two rectangular prisms:
bottom - 9 in. by 2 in. by 4 in.
top - 5 in. by 2 in. by 4 in.
total volume = 9 in. × 2 in. × 4 in. + 5 in. × 2 in. × 4 in.
total volume = 112 in.³
