Let's make the length L and the width w. So, here's what we know:

L = 2w + 10

Lw = 1500

Substitute L in as 2w + 10:

w(2w + 10) = 1500.

Simplify.

2w squared +10w = 1500

Make it a quadratic equation, w = 25 or -30. Since it can't be negative, w = 25.

1500/25 = 60.

Length = 60
Width = 25

What temperature is 15 degrees lower than 7degrees
BabaBlast [244]
15 degrees lower than 7 degrees means that we have to subtract.

So we have 7 degrees and it wants 15 degrees lower, so we would do 7 - 15

And so 7-15 = -8

So 15 degrees lower than 7 degrees would be -8 degrees. :)

¿Cuál es el área de un rectángulo, sabiendo que su perímetro mide 24 cm y que su base es el triple de su altura?
Brrunno [24]

Answer:

El área del rectángulo es:

27 cm²

Step-by-step explanation:

Consideración:

La formula del perímetro de un rectángulo es:

p = 2(altura + base)

Planteamiento:

24 = 2(a+b)

b = 3a

a = longitud de la altura del rectángulo

b = longitud de la base del rectángulo

Desarrollo:

sustituyendo el valor de la segunda ecuación del planteamiento en la primer ecuación del planteamiento:

24 = 2(a + 3a)

24/2 = 4a

12 = 4a

a = 12/4

a = 3 cm

de la segunda ecuación del planteamiento:

b = 3a

b = 3*3

b = 9 cm

Comprobación:

de la primer ecuación del planteamiento:

24 = 2(3+9)

24 = 2*12

Respuesta:

la formula del área de un rectángulo es:

A = base * altura

A = 9cn * 3cm

A = 27cm²
