(3x +3) (x - 4)
3x(x - 4) + 3(x - 4)
3x^2 - 12x + 3x - 12
3x^2 - 9x - 12
Answer:
x ^2+
y^
2
=
25
Step-by-step explanation:
Square both sides:
r
^2
=
5^
2
Substitute x
^2
+
y^
2 for r
^2
:
x
^2+
y
^2
=
5
^2
Insert the center -0 into the x and y terms:
(
x
−
0
)^
2
+
(
y
−
0
)
^2
=
5
^2
This is the standard form for a circle whose center is (
0,
0
) and the radius is 5.
Answer:
All of them.
Step-by-step explanation:
They can all be written as a fraction a/b.
The zeros are 5/2 and -4/5, I think.
The equation I came up with for this one would be 64=12+2x. When you solve this equation start with subtracting twelve, than take 52 (64-12) and divide it by two to figure out how many days it has been (26 days). Hope this helps!
