Answer:
<h3>The answer is 10.2 units</h3>
Step-by-step explanation:
The distance between two points can be found by using the formula

where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
U (7,-4) and V(-3,-6)
The distance between them is

We have the final answer as
<h3>10.2 units to the nearest tenth</h3>
Hope this helps you
If your using pemdas the answer would be roughly 3.6 because you divide 8 and 3 first to get 2.6 repeated then do 2+2=4 then 4-3=1 + the original 2.6 = 3.6
X2 + 14X = -49
+49
x2 + 14X + 49
(x2 + 14X + 7) + 49 - 7 = 0
(X+7)2 + 42 = 0
- 42
(x+7)2 = 42
*square root of both sides)
X + 7 = square root of 42
-7
X = -7 +/- square root of 42
x = -13.48
x = -0.52
and for b, without doing any work my guess is because there is a 0 under the radical, which gives you only one real solution
