What is the perimeter of the figure

anastassius [24]

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

$P=23+22.7+13.7+14$

$P=73.4\ units$

5y-3x=25 solve for y

pshichka [43]

Answer:

$y=\frac{3}{5} x+5$

Step-by-step explanation:

$5y-3x=25\\\\5y-3x+3x=25+3x\\\\5y+0=3x+25\\\\5y=3x+25\\\\\frac{1}{5} (5y)=\frac{1}{5} (3x+25)\\\\y=\frac{1}{5}(3x)+\frac{1}{5}(25) \\\\y=\frac{3}{5}x+5$

Answers with explanations

Snezhnost [94]

To answer this question, try to solve the system of equations. Start by plugging in " $x^{2} +3x-7$ " in for y in the second equation:

$x^{2} +3x-7-5x+8=0$

*Combine like terms*

$x^{2} -2x+1=0$

*Factor*

$(x-1)(x-1)=0$

*Set each term equal to 0*

x-1=0

*Add 1 to both sides*

x=1

C) There is exactly 1 solution.

Hope this helps!!
