I'll assume the question is: what's the volume?
It's two L×W×H rectangular prisms (aka boxes) put together
The bottom one is 2×3×4
The top one is 5×4×1
Volume = 2×3×4 + 5×4×1 = 24 + 20 = 44
Answer: 44 cubic feet
we know that a has to be a number less than 0 and c has to be a number greater than 0. so a has to go before the number 0 and b can go before or after 0, as long as it satisfies the equation
Replace b with 7 in the binomial and simplify.
b + 16
Let b = 7
7 + 16 = 23
