Answer: 21
Step-by-step explanation:
Answer:
49 cm²
Step-by-step explanation:
Formula for area:
a = l (length) x w (width)
if its 7 cm on each side, then the length and width will be 7
7*7 = 49 cm²
We have that

Let y be the first root, then y - 6 will be the second one. Since both roots make the quadratic equation equal to 0, we have that:

Solve for y:

Plug in y = 5/2 into original quadratic equation and solve for c:

So, the answer is
c = -35/4
67.8: 6.78, 0.678, 0.0677
456.8: 45.68, 4.568, 0.4568
531.20: 53.12, 5.312, 0.5312
The pattern here is that the number of 0s there are in the digit of whatever you are dividing by, that is how many places you move the decimal place to the right. For example, by dividing 67.8 by 100, the decimal place has been moved 2 places to the right, resulting in the number 0.678
Full bubble at 0, then make it go right.
