Answer:
8/35 cubic inches
Step-by-step explanation:
Volume is length x width x height. To find the answer, we must multiply all values together. 2/3 times 3/5 ix 6/15. Let's simplify this before multiplying further. 6/15 can also be written as 2/5. 2/5 times 4/7 is 8/35 which cannot be simplified. 8/35 is the final answer.
Answer:
42
Step-by-step explanation:
Answer:
3x^2 + 7xy + 5
Step-by-step explanation:
Let the shortest side = X and the longer = 4X
perimeter = (length + width) ×2
30 = (4X + X)×2
30 = 8X + 2X
30 = 10X divide 10 to both sides
3 = X
the longer side = 4X = 4 × 3 = 12 cm
the shortest side = X = 3 cm
area = length × width
area = 3×12 = 36 cm^2
