Answer:

∠JKL = 108°

Step-by-step explanation:

1.) Add 3x + 15 and 2x + 10 for 180

→ (3x + 15) + (2x + 10) = 180

2.) Add common factors

→ 5x + 25 = 180

3.) Solve for x

→ x = 31

4.) Replace x with 31

→ 3(31) + 15 = 108

∠JKL = 108°

TO CHECK

1.) Replace x with 31

→ 2(31) + 10

2.) Add 108 and 72 to get 180

→ 108 + 72 = 180

Answer:

m<jkl =0

Step-by-step explanation:

step 1: keep it ir mind that angle jkl and angle lkm are equal

step 2: since they are equal thus:

m<jkl= m<lkm

3x + 15= 2x + 10

3x-2x= 10-15

x = -5

Step 3: substitute x= -5 in m<jkl

3(-5)+15

-15+15 = 0

therefore your answer for both anhle should be 0

Una persona asegura que su casa tiene forma rectangular y que el perímetro de la misma es de 18 m y que además, su área es de 21
leva [86]

Considerando las fórmulas para el perímetro y el área de un rectángulo, hay que se chega en una <u>eccuación cuadrática sin solución</u>, o sea, las medidas no son posibles y la persona estaba mintiendo.

<h3>¿Cuál es la fórmula para el perímetro y el área de un rectángulo?</h3>

Considerando que las dimensiones son l y w, hay que:

  • El perímetro es: P = 2(l + w).
  • El área es: A = lw.

El <u>perímetro es de 18 m</u>, o sea:

2(l + w) = 18

l + w = 9

l = 9- w.

El <u>área es de 21 m²</u>, o sea:

lw = 21

(9- w)w = 21

-w² + 9 - 21 = 0

w² - 9w + 21 = 0

El discriminante es dado por:

D = 9² - 4 x 1 x 21 = -3.

El discriminante negativo implica que la <u>eccuación cuadrática no tiene solución</u>, o sea, las medidas no son posibles y la persona estaba mintiendo.

BARSIC [14]

A

Step-by-step explanation:

First and foremost, we can rule out B and C because they are less than one and would make the hexagon smaller instead of bigger. Now, when we measure the units, we see that it goes up by 2 squares on the graph. So, by process of elimination and measurement, we get the answer of A.
