Answer:
The product of the Width and Length is x^2 + 4x + 3 cm^2.
Step-by-step explanation:
The volume of a box = 5x^3 + 20x^2 + 15x cm^3.
Volume of a Box = W*L*H [Width(W), Length(L), and Height(H)]
W*L*(5x) = 5x^3 + 20x^2 + 15x cm^3
W*L = (5x^3 + 20x^2 + 15x cm^3)/5x cm
W*L = x^2 + 4x + 3 cm^2
We know the area of the base of the box (W*L). It is x^2 + 4x + 3 cm^2.
To find the actual width and length, we need to know one of the variables, L or W. Without that, all we can say is that their product (W*L) is x^2 + 4x + 3 cm^2.
Subtract the total cost by the banana cost and divide what you get by the apple cost
Solve
First, place the unknown x on the left.
Then, solve for x.
What must be subtracted from each term of the ratio 3:7 so that the ratio becomes 2:5?
My attempt: Let two numbers be 3x and 7x. So, 3x−y7x−y=25⟹15x−5y=14x−2y⟹y=x3. But the answer is given as 13 only.
I wish somebody could provide some clarifications.
The greatest place is the digit all the way to the left, so the answer would be 30 b/c 6 is closer to 10 so you add 10 to 20 bc 20 is the greatest place
