Answer:

The length of Side RT of the polygon is 7\ units

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

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

we have

R(-6,2)\\T(1,2)  

substitute the values

d=\sqrt{(2-2)^{2}+(1+6)^{2}}

d=\sqrt{(0)^{2}+(7)^{2}}

dRT=7\ units

Answer:  The length of side RT is 7 units.

Step-by-step explanation:  Given that the co-ordinates of vertices R and T for a polygon on a co-ordinates plane are R(−6, 2) and T(1, 2).

We are to find the length RT of the polygon.

We know that

the length of a line segment with endpoints P(a, b) and Q(c, d) is equal to the distance between the points P and Q.

By distance formula, the distance between P(a, b) and Q(c, d) is

D=\sqrt{(c-a)^2+(d-b)^2}.

So, the distance between R(−6, 2) and T(1, 2) is given by

RT=\sqrt{(1+6)^2+(2-2)^2}=\sqrt{49+0}=7.

Thus, the length of side RT is 7 units.

Charra [1.4K]

Answer:

$6.4

Step-by-step explanation:

You just do 32 × .2 to give you the discount of 6.4

You multiple by .2 because 20% as a decimal is .2 ( you do 20% divided by 100 to give you .2)

PLEASE ANSWER I WILL MARK THE BRAINIEST ANSWER :)<br><br>factorise: X^2 + 10x + 16
Damm [24]

Answer:

(x+2)(x+8)

Step-by-step explanation:

1.)find factors of the third expression(16)that will add up to give the second expression(10)

16=2×8. 10=2+8

2.)substitute those factors inplace of 10

{x}^{2}  + 10x + 16

x {}^{2}  + 2x + 8x + 16

3.)factorise using grouping method

( {x}^{2}  + 2x) + (8x + 16)

x(x + 2) + 8(x + 2)

= (x + 2)(x + 8)

(3x-9) +(x+19)+x=180
5x+10=180
-10=-10
5x=170
5 = 5
x=34

2x+(2x+10)+x=180
5x+10=180
-10=-10
5x=170
5 = 5
x=34

yes they are similar
