The equation in the form (x + a)² = b is (x + 2)² = 16
<h3>How to determine the intermediate step?</h3>
The equation is given as:
x² + 4x = 12
Take the coefficient of x
k = 4
Divide by 2
k/2 = 2
Square both sides
(k/2)² = 4
Add this result to both sides of x² + 4x = 12
x² + 4x + 4 = 12 + 4
Evaluate the sum
x² + 4x + 4 = 16
Express as a perfect square
(x + 2)² = 16
Hence, the equation in the form (x + a)² = b is (x + 2)² = 16

Step-by-step explanation:
6m+15n-12p/n where m=-3.5, n=4 and p=3
6(-3.5)+15(4)-12(3)/4=-21+60-36/4
-21+60-9=-30+60=30
Answer:
The answer is A!
Step-by-step explanation:
It is linear even though you see no y-intercept, the y- intercept it 1.
(Prolly won't makes sense but it's A because I got it right)
I believe the answer would be your 3rd choice. C.
Answer:
Step-by-step explanation:
if x>−12
add 12 : x+12 >0
but x−(−12) = x+12
so :|x−(−12)| = |x+12| = x+12 .... ( x+12 >0)
note : |a| = a if a>0
