Answer this please :)

Step-by-step explanation:

Distance formula: D = Square root (x^2-x^1)^2+(y^2-y^1)^2

H(-3,-4) Q(-8,1)

  x1  y1.   x2 y2  

Plug in umbers

(-8+3)^2+(1+4)^2

(-5)^2 + (5)^2

25 + 25

Square root of 50 = 7.07106781187

7.1

Square root was always there I just don't know how to put it on a laptop.

Hope this helps!

:)

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
