Answer:

Option B, 14.6 units

Step-by-step explanation:

Step 1: Find the distance of AB

$AB =$ $\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

$AB =$ $\sqrt{(3 - 1)^2 + (5 - 3)^2}$

$AB =$ $\sqrt{(2)^2 + (2)^2}$

$AB =$ $2\sqrt{2}$ or 2.83...

Step 2: Find the distance of BC

$BC =$ $\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

$BC = \sqrt{(3 -1)^2 + (-1 - 3)^2}$

$BC = \sqrt{(2)^2 + (-4)^2}$

$BC = \sqrt{4 + 16}$

$BC = \sqrt{20}$

$BC = 2\sqrt{5}$ or 4.47...

Step 3: Find the perimeter

AB is the same as AD and BC is the same as DC

$2(AB) + 2(BC)$

$2(2.83) + 2(4.47)$

$5.66 + 8.94$

14.6 units

< 3 de 13 Suppose f(x)=2x3+11x2 18x+9 has a zero at -3. What are the other solutions?

Georgia [21]

Answer: x ≓ 6.899067609

Step-by-step explanation:

Easy because:

(2 • (x3)) - 11x2) - 18x) - 9 = 0

(2x3 - 11x2) - 18x) - 9 = 0

2x3 - 11x2 - 18x - 9 = 0

2x3-11x2-18x-9 = 0

F(x) = 2x3 - 11x2 - 18x - 9

At x= 6.00 F(x) is equal to -81.00

At x= 7.00 F(x) is equal to 12.00 F( 6.899067609 ) is -0.000000436

Please, for me? I need to pass my math class.

Ede4ka [16]

Answer: Black

Step-by-step explanation: I feel like the higher the line is on the graph, the farther they have moved, so since the black line is the lowest, it might be Noah.

Hope this helps!
