Answer:
Step-by-step explanation:
Solution by completing the square for:
x2−12x+9=0
Keep x terms on the left and move
the constant to the right side
by subtracting it on both sides
x2−12x=−9
Take half of the x term and square it
[−12⋅1/2]^2=36
then add the result to both sides
x^2−12x+36=−9+36
Rewrite the perfect square on the left
(x−6)^2=−9+36
and combine terms on the right
(x−6)^2=27
Take the square root of both sides
x−6=±27−−√
Simplify the Radical term (1):
x−6=±3–√3
Isolate the x on the left side and
solve for x (1)
x=6±3–√3
therefore (2)
x=6+3–√3
x=6−3–√3
which becomes
x=11.1962
x=0.803848
that's a line graph it show how high or low the levels of anything is
HOPE IT HELPS
First, we find the area of the triangle is 12 in. Square. Then, we find the area of the square is 100 square inches. Finally, we add it together to have 112 square inches.
OMG I HATE I-READY SO MUCH
Could you take a picture of the whole question?
Ok ima try
a x 3 + c x 2 = 14
This is how I learned please don’t roast me if I do it wrong
