Answer:

Option A.

$P=73.4\ units$

Step-by-step explanation:

see the attached figure with letters to better understand the problem

In this problem we have a triangle with a circle inscribed in it

$A.F=A.B\\C.B=C.D\\E.F=E.D$

step 1

Find the length side B.C

$C.B=A.C-A.B$

substitute the given values

$C.B=23-14=9\ units$

step 2

Find the length side C.D

Remember that

$C.D=C.B$

therefore

$C.D=9\ units$

step 3

Find the length side E.D

we know that

$E.D=E.C-C.D$

substitute the given values

$E.D=22.7-9=13.7\ units$

step 4

Find the length side E.F

Remember that

$E.F=E.D$

therefore

$E.F=13.7\ units$

step 5

Find the length side A.F

Remember that

$A.F=A.B$

therefore

$A.F=14\ units$

step 6

Find the perimeter

$P=23+22.7+13.7+14$

$P=73.4\ units$

Svetach [21]

Step-by-step explanation:

3×3=9. 3 faces so 9×3=27

10×3=30. 4 faces so 30×4=120

6×3=18. 2 faces so 18×2= 36

15×3=45. 3 faces so 45×3= 135

120+135=255

36+27=63

255+63=318

answer =318

What is 0.26 repeating (.26 reappearing) as a fraction in simplest form?

IRISSAK [1]

<span>Is it 0.262626...?
repeating decimals you have to write at least two of the repeats so it is obvious what is repeating.

1000x = 262.62626...
10x = 2.62626...
1000x - 10x = 260
990x = 260
x = 26/99</span>

Algebra tiles to prove that 4 + 8x and 4(2x+1)

Dafna1 [17]

Not sure what algebra tiles are

not sure how to absolutely prove
I can prove it works at least most of the time by subsitute ing number for x

remember that 0,1,2 have special properties and are not very good for subsituting so
try 4
4+8(4)=4(2(4)+1)
true or false?
4+8(4)=4(2(4)+1)
multipily
4+32=4(8+1)
36=4(9)
36=36
this is treu at least for the number 4
another way is to believe in the distributive property where
a(b+c)=ab+ac so then
4(2x+1)=4(2x)+4(1)=8x+4=4+8x

Find the slope of the line that passes through the two points.<br> (12,-5) and (10,-4)

hichkok12 [17]

Given parameters:

First point = (12, -5)

Second point = (10, -4)

Unknown:

Slope of the line = ?

Slope is simply the vertical rise divided by the horizontal distance.

Slope = $\frac{Rise }{horizontal distance}$

Simply to find slope;

Slope = $\frac{y_{2} - y_{1} }{x_{2} - x_{1} }$

First point = (12, -5), x₁ = 12 and y₁ = -5

Second point = (10, -4), x₂ = 10 and y₂ = -4

Input the parameters:

Slope = $\frac{-4 -(-5)}{10 - 12}$

= $\frac{-4 + 5}{-2}$

= - $\frac{1}{2}$

The slope of the line is - $\frac{1}{2}$
