Answer: -7
Step-by-step explanation: x=3 and y=2
Answer:
Product of 6 and a number would be 6.
Nine more than a number?
Combine a number and 7? Either 7x or x + 7.
Step-by-step explanation:
Question 1 is relatively simple. 6 is a constant, so it can be inserted into any equation and maintain the same value. "A number" could represent anything, so we'll represent it with a variable. This gives you 6x (also 6*x)
Question 2 is the same as the first with 1 more step added to it. A number, as previously stated, is represented by the variable x. You divide this by the constant value of 2 to give you . Nine more would add +9 to the expression. Your final answer would be .
Question 3. Combine is a bit vague, but it could be either addition or multiplication. This could give you either or .

Answer:
-7.2
Step-by-step explanation:
If you notice, the figure has two hexagonal faces and 6 rectangles.
now the rectangles are just 4x9 each, so their area is just 6(4*9) for all 6.
the hexagons has a
distance from the center perpendicular to a side of 7.8, namely the
apothem is 7.8, and since each side is 9 km long, the perimeter is 9+9+9+9+9+9.
since the area of a regular polygon is (1/2)(apothem)(perimeter), we can simply get the area of those two hexagons and the area of the rectangles, sum them up, and that's the surface area of the hexagonal prism.
