Answer:

<h2>P=4+√5+√13 the answer is C</h2>

Step-by-step explanation:

to find the perimeter , need to find the length(distance of the sides)

D=√(x2-x1)²+(y2-y1)²

D between BE and BD and ED

d of BE :

B(1,2) E(5,2)

D of BE = √(5-1)²+(2-2)²=√4²=4

D of BD : (1,2) , (2,4)

D=√(2-1)²+(4-2)² = √1²+2² = √5

ED : (5,2) , (2,4)

d=√(2-5)²+(4-2)²=√-3²+2² =√13

the perimeter= BE+BD+ED

I believe the answer would be C, but I'm not sure.

Solve the system of equations. <br><br> 10x+y=−20 <br><br> y=2x2−4x−16<br><br> ( , ) and ( , )

Sladkaya [172]

I will go about solving this using the elimination method.

First, convert the equations.

10x + y = -20
4x + y = -12

Second, find the easiest variable to get rid of and get rid of it! (In this case, y) We will subtract to get rid of y.

6x = -8

Third, you want to solve the equation.

6x = -8 (divide by 6)
x = $-1 \frac{1}{3}$

Fourth, solve for y by inserting the answer for x into one of the equations.

10( $-1 \frac{1}{3}$ ) + y = -20
$-13 \frac{1}{3}$ + y = -20 (subtract $-13 \frac{1}{3}$ )
y = $-6 \frac{2}{3}$

The solution for this system of equations is ( $-1 \frac{1}{3}$ , $-6 \frac{2}{3}$ ).
