The segments shown below could form a triangle

True.

For a triangle to have one interior (closed figure), the sum of two of its sides has to be greater than the other side. This rule applies to every combination of the triangle. 8+1=9, which is greater than 8. 8+8=16, which is greater than 1. Since every combination works, these segments can form a triangle.

kotegsom [21]

Answer: The same trip will require 3.8 hours.

Step-by-step explanation:

Since we have given that

Time = $4\dfrac{1}{2}=\dfrac{9}{2}$

Speed = 55 mph

So, distance would be

$Speed\times time=55\times 4.5=247.5\ miles$

If the speed limit = 65 mph

So, time will be

$\dfrac{247.5}{65}=3.8\ hours$

Hence, the same trip will require 3.8 hours.

Answer:

x = -6 x = -1

Step-by-step explanation:

x^2 + 7x + 6 = 0

Factor

What two numbers multiply to 6 and add to 7

6*1 = 6

6+1 = 7

(x+6) (x+1) =0

Using the zero product property

x+6 = 0 x+1 = 0

x+6-6 =0 -6 x+1-1 = 0-1

x = -6 x = -1

Rickey has been commissioned to paint a mural that is allowed to have an area of 50 square meters. To make the rectangle shape o

Leno4ka [110]

Answer:

12.808 meter is the length should Rickey use for the mural.

Step-by-step explanation:

Area of the mural = A = $50 m^2$

Length of the mural = l

Width of the mural = w

l = 5 + 2w

Area of the rectangle = l × w

$A=(5+2w)\times w$

$50 m^2=5w+2w^2$

$2w^2+5w-50=0$

Solving above equation with the help of Completing squares method:

$(\sqrt{2}w)^2+2\times \sqrt{2}w\times \frac{5}{2\sqrt{2}}+(\frac{5}{2\sqrt{2}})^2-50=(\frac{5}{2\sqrt{2}})^2$

$(a+b)^2=a^2+b^2+2ab$

$(\sqrt{2}w+\frac{5}{2\sqrt{2}})^2=(\frac{5}{2\sqrt{2}})^2+50$

$(\sqrt{2}w+\frac{5}{2\sqrt{2}})^2=\frac{25}{8}+50$

$(\sqrt{2}w+\frac{5}{2\sqrt{2}})^2=\frac{425}{8}$

$(\sqrt{2}w+\frac{5}{2\sqrt{2}})=\pm\sqrt{\frac{425}{8}}$

w = 3.904 m (accept)

w = -6.404 m (reject)

l = (5 + 2w)m = 5 + 2 × (3.904) m= 12.808 m

12.808 meter is the length should Rickey use for the mural.
