pentagon [3]3 years ago
8 0

Answer:

1) k = (-8)/5

2) x = 5

Step-by-step explanation:

1)

6 {k}^{2}  + 16k = 0

=  > 2k(3k + 8) = 0

=  > 3k + 8 =  \frac{0}{2k}  = 0

=  > 3k =  - 8

=  > k =  \frac{ - 8}{3}

2)

{x}^{2}   - 5x = 0

=  > x(x - 5) = 0

=  > x - 5 =  \frac{0}{x}  = 0

=  > x = 5

The figure below shows a tent with wires attached to help stabilize it. The length of each wire is 8 feet greater than the dista
Anestetic [448]

Answer:

The length of 2 wires are 13 feet and 12 feet [i don't know if the 3rd side is a wire, if so, the length is 5 feet]

Step-by-step explanation:

<em>The image of the tent is attached.</em>

<em />

As we can see, it creates a right triangle with "x+8" side being the hypotenuse of the triangle.

The pythagorean theorem tells us:

Hypotenuse^2 = Leg^2 + Leg^2

THe hypotenuse is "x+8", the two legs are "x" and "x+7" respectively. Let's solve for x:

(x+8)^2=(x+7)^2+x^2

We expand and solve for x:

(x+8)^2=(x+7)^2+x^2\\x^2+16x+64=x^2+14x+49+x^2\\x^2+16x+64=2x^2+14x+49\\x^2-2x-15=0\\(x-5)(x+3)=0\\x=5,-3

Length can't be negative, so x = 5.

Hence, the 3 sides of the triangle are:

x = 5

x + 8 = 13

x + 7 = 12

The length of 2 wires are 13 feet and 12 feet
