There's actually a secret trick to doing it without using the complete the square method. There's a formula and it always works. My teacher taught me it and I used it a lot in the ALG1 EOC and was VERY helpful. I guess ur prepping for the eoc ri xD
So the "hack" is the first 2 attachments.
it's important to know the typical method, so the typical one is the last attachment
Answer:
A
Step-by-step explanation:
The simpler way to calculate this question is just to calculate A and B
A - 4 x (7+2) = 4 x 9 = 36
B - (4 x 7) + 2 = 28 + 2 = 30
A = 36
=> Thus, our answer is A

We can ise Pythagorean triplet which is ( 12 , 16 , 20 )
Therefore the answer is 16.
Step-by-step explanation:
Or we can use Pythagoras theorem , stated as ;
( hyp )^2 = ( adj )^2 + ( opp )^2
hyp ( hypotenuse ) = 20
We can assume the adj ( adjacent ) = 12
By substituting the values ,
20^2 = 12^2 + ( adj )^2
400 = 144 + ( adj )^2
400 - 144 = ( adj )^2
256 = ( adj )^2
Take the square root of both sides
✓256 = adj
16 = adj
Therefore the length of the other leg which is the adjacent( adj ) side is 16.
