We have

.
We add 6 to both sides.

.
Now, to solve for

, we factor out and divide by a 9 to get

.
Answer:
12
Step-by-step explanation:
we would do 475 divided among 40
475/40=11.875
but we would not use 11.875 so let's make it 12$
Answer:
i think it would be 9cm for each piece
Step-by-step explanation:
i did 12 times 6 which was 72 then i divided by 8 and got 9 so i think that might be the answer.
This is defined as a binary operation, the elementary arithmetic operation of subtraction. Other operations involving two real numbers are addition, multiplication, and division; in contract unary operations involve only one number and come in the form of trigonometric functions and negation, for example.
Check the picture below
so.. .hmmm the vertex is at the origin... and we know the parabola passes through those two points... let's use either.. say hmmm 100,-50, to get the coefficient "a"
keep in mind that, the parabolic dome is vertical, thus we use the y = a(x-h)²+k version for parabolas, which is a vertical parabola
as opposed to x = (y-k)²+h, anyway, let's find "a"

now.. .your choices, show.... a constant on the end.... a constant at the end, is just a vertical shift from the parent equation, the equation we've got above.. is just the parent equation, since we used the origin as the vertex, it has a vertical shift of 0, and thus no constant, but is basically, the same parabola, the one in the choices is just a shifted version, is all.
