Answer:
(2a-1)^2
Step-by-step explanation:
Rewrite 4a^2 as (2a)^2
.
(2a)^2−4a+1
Rewrite 1
as 12
.
(2a)^2−4a+1^2
Check the middle term by multiplying 2ab
and compare this result with the middle term in the original expression.
2ab=2⋅(2a)⋅−1
Simplify.
2ab=−4a
Factor using the perfect square trinomial rule a^2−2ab+b^2=(a−b)^2
, where a=2a and b=−1
.
(2a−1)2
please brainly
Answer:
x = -5/P
Explanation:
We are given
Px + 17 = 12
Subtract 17 on both sides using the Subtraction Property of Equality
Px = -5
Divide both sides by P to isolate *x* by itself using the Division Property of Equality
x = -5/P
Answer:
Since there are 4.5*10^2 grams of trash per day per person, we multiply that by 3.2*10^6 for everyone in the US and then multiply that by 365 to get how much in a year, which is 525600000000 or 5.256*10^11 (I think it's 11)

Answer:
(0, ±2√5)
Step-by-step explanation:
The foci are the points on the major axis that are the length of the semimajor axis away from the co-vertices.
Here, that means their y-coordinate is ±√(36-16) = ±√20 = ±2√5.
The x-coordinate is that of the major axis, x=0.
1,004. Take the 2006 number and subtract the 2004 number and that will be your answerz
