A = lw
7x³ - 42x² = l(7x²)
7x²(x) - 7x²(6) = l(7x²)

Shane decided to dig his garden.On the first fine day,he dug 1/3 of it.On the second day he dug only 1/4 of it before it started

Answer:

I think 1/4

Step-by-step explanation:

So, you first should find a common denominator so you can add the fractions together.

So, 1/4 + 1/3 + 1/6 becomes 3/12+4/12+2/12.

Add that up, you get 9/12.

Simplify.

9/12 = 3/4

3/4 is how much is dug out. 4/4 - 3/4 is 1/4. That's how much for digging is left, I believe.
