Answer:

15 units

Step-by-step explanation:

K(8, 6) and J(-4, -3)

Distance between 2 points

$= \sqrt{(x1 - x2)^{2} + {(y1 - y2)}^{2} }$

Thus using the formula above,

distance between points J and K

$= \sqrt{ {[8- (-4)]}^{2} + {[6- (-3)]}^{2} } \\ = \sqrt{ {12}^{2} + {9}^{2} } \\ = \sqrt{225} \\ = 15 \: units$

guapka [62]

Answer:

2.55

Step-by-step explanation:1

Convert 1121\frac{1}{2}121 to improper fraction. Use this rule: abc=ac+bca \frac{b}{c}=\frac{ac+b}{c}acb=cac+b.

34+3.3−1×2+12\frac{3}{4}+3.3-\frac{1\times 2+1}{2}43+3.3−21×2+1

Simplify 1×21\times 21×2 to 222.

34+3.3−2+12\frac{3}{4}+3.3-\frac{2+1}{2}43+3.3−22+1

Simplify 2+12+12+1 to 333.

34+3.3−32\frac{3}{4}+3.3-\frac{3}{2}43+3.3−23

Simplify.

5.12\frac{5.1}{2}25.1

Simplify.

Solve the problem please

Molodets [167]

Answer:

x = 9±sqrt(7)

Step-by-step explanation:

3(x-9)^2 =21

Divide each side by 3

3/3(x-9)^2 =21/3

(x-9)^2 =7

Take the square root of each side

sqrt((x-9)^2) =±sqrt(7)

x-9 =±sqrt(7)

Add 9 to each side

x = 9±sqrt(7)
