Answer:

AB = CD

5 - x^2 = -6x + 13

- x^2 - 8 = -6x

- x^2 + 6x - 8 = 0

x^2 - 6x + 8 = 0

Because 2 * 4 = 8 and 2 + 4 = 6

the solutions are

x = 2 or x = 4

You can also use the pq or abc-formula to solve a quadratic equation.

What is the distance between A and B? Round your answer to the nearest tenth.
algol [13]
Distance formula : sqrt (x2 - x1)^2 + (y2 - y1)^2
(-1,5)....x1 = -1 and y1 = 5
(4,1)...x2 = 4 and y2 = 1
now we sub and solve
d = sqrt ((4 - (-1)^2 + (1 - 5)^2)
d = sqrt ((5^2 + (-4^2))
d = sqrt (25 + 16)
d = sqrt 41
d = 6.4 <=== ur distance

(25 + 19) + 15 = (19 + 25) + 15<br><br><br> What property is that equation
malfutka [58]

Answer:

Commutative Property

Step-by-step explanation:

It looks like Associative property which is when you change the GROUP, but actually it’s commutative because it didn’t change any numbers in the group, just the order of where they were.

Associative: (25 + 19) + 15 = (15 + 19) + 25

Commutative: (25 + 19) + 15 = (19 + 25) + 15

It didn’t change the numbers, only the order. Therefore, it would be commutative property
