Answer:
Step-by-step explanation:
d = sqrt ((x2 - x1)^2 + (y2 - y1)^2)......this is ur equation
(9,-2)....x1 = 9 and y1= -2
(6,3)....x2 = 6 and y2 = 3
d = sqrt ((6 - 9)^2 + (3 - (-2)^2)
d = sqrt ((-3^2) + (5^2))
d = sqrt (9 + 25)
d = sqrt (34)
d = 5.83
Answer:
5,83
Step-by-step explanation:
AC = 3-(-2) = 5
BC = 9 - 6 = 3
AB^2 = AC^2 + BC^2
AB^2 = 5^2 + 3^2
AB^2 = 25 + 9
AB^2 = 34
AB = sqrt(34)
AB = 5,83
Done :))
Answer:
124
Step-by-step explanation:
31 * 4 = 124
124 * 1/4 = 31
Answer:
3x^2 - x - 10 = 0
3x^2 - 6x + 5x - 10 = 0
3x(x - 2) + 5(x - 2) = 0
(3x + 5)(x - 2) = 0
x = -5/3 , 2
Step-by-step explanation:
mark me brainliest please
3x² - x = 10
3x² - x - 10 = 0
Δ = b² - 4.a.c
Δ = -1² - 4 . 3 . -10
Δ = 1 - 4. 3 . -10
Δ = 121
There are 2 real roots.
x = (-b +- √Δ)/2a
x' = (--1 + √121)/2.3
x'' = (--1 - √121)/2.3
x' = 12 / 6
x'' = -10 / 6
x' = 2
x'' = -5/3
