Answer:
Six squared=36
Step-by-step explanation:
Well, we know squared means 2
So...Think.
Six is not times 2. You might think that, but...
...It's actually multiplying 6 two times
6x6 is 36
You also can think of it as
6x(6 two times)
or 6x(3x2)

Answer:
d = 0.33
Step-by-step explanation:
First off, you want to get like terms next to each other. We'll move the numbers with variables on one side and normal numbers on the other. Since we're changing the sides of the equal sign they're on, this also changes whether their positive or negative.
d - d - 2d + 3d = 10 -7 + 8 - 10
Now that they're together, we can add or subtract them. The variables without numbers can be ones for this equation.
3d = 1
Now we divide 1 by 3 to find what d equals.
3d/3 = 1/3
d = 0.33
I believe the answer you are looking for is the quadratic formula. because it has the formula correct, and it to me just looks exactly like it.
So, it has the ax^2+bx+c=0 but just a little difference, it has a subtracting sign instead of adding.
I don't know if I am right, but that is my guess. I remember doing those lol
