Step-by-step explanation:
You can use the quadratic formula to find the roots.
Answer:

Step-by-step explanation:
- Since 2 opposite add up to 0,remove them from the expression (+4ab, - 4ab)
2. Calculate the product
Answer:
22.81
Step-by-step explanation:
The distance formula can be used to find the distances between pairs of vertices. The perimeter is the sum of those distances.
<h3>Side lengths</h3>
The distance formula is ...
d = √((x2 -x1)^2 +(y2 -y1)^2)
Using this formula the triangle side lengths are ...
AB = √((6 -(-2))^2 +(2 -2)^2) = √(8^2) = 8
BC = √((0 -6)^2 +(8 -2)^2) = √(6^2 +6^2) = 6√2
CA = √((-2 -0)^2 +(2 -8)^2) = √(4 +36) = √40
The perimeter of the triangle is the sum of these lengths:
P = 8 +6√2 +2√10 ≈ 22.8098
The perimeter is about 22.81 units.
Answer:
y = x + 5
Step-by-step explanation:
Slope = - 1
Slope of the perpendicular line = 1
Point (2,7)
(b) y-intercept= 7 - (1)(2)
= 5
