Answer: Choice B) 
We have some value m and we're squaring it to get 
To undo this and isolate m, we apply the square root to both sides
There are two solutions here. This is similar to how there are two solutions in something like 
(those two solutions being x = 5 and x = -5). Squaring any negative number leads to a positive result because
negative times negative = positive.
Answer:
$435.3
Step-by-step explanation:
Assuming simple interest
Interest, I=Pi/100 where P is principal amount and i is rate of interest in percentage
For $3500, the interest will be 3500*2.2/100=$77
From total target of $151, the person is less 151-77=$74
Taking x as principal and rate of interest as 17% then
0.17x=74
X=74/0.17=$435.2941176470
Rounded off as $435.3
54981.35 is the square root
Answer:
A. Definition of linear pair
Step-by-step explanation:
A linear pair of angles is formed when two lines intersect. Since angle on a straight line = 180°, angles of a linear pair sum up to 180°.
angles 1 and 4, angles 2 and 5, angles 3 and 6 are all linear pairs. Each pair = 180°.
