Answer:
16
Step-by-step explanation:
The dimensions of the base of the prism are 4" by 2"; the height is 2".
Looking at the base, we see that (4)(2), or (8) 1" cubes would cover it exactly and wholly. We'd have a 3-dimensional prism with one layer of 1" cubes.
Now if we add a second layer right on top of the first layer, we'd have used (16) 1" cubes.
$42.60. You multiply 35.50 by .20 (that's decimal version of 20%) which equals 7.10. Then you add 35.50+7.10=42.60
You should purchase from the store that is selling the 2/$5. You spend less money per item. The A store has you pay $2.50 per item with the deal while the B store has you pay almost $6 per item.
Answer:

Step 2: Find <em>x </em>roots
5x + 7 = 0
x = -5/7
x - 2 = 0
x = 2
