Answer:

The shorter piece is 4 in. long.

Step-by-step explanation:

The length of the shorter piece can be represented using x.

Thus, you can say that the longer piece is 2x (since it is twice as long as the other piece).

Since, the length of both the pieces will, for sure, add up to 1 ft, then we can say:

x + 2x = 1 ft

Which will simplify into:

3x = 1 ft (Divide both sides by 3)

x = 4 in. (Since 1 ft = 12 in., we can express it in different units unless you want a non-terminating decimal)

x = 4 in. is the length of the shorter piece since we established that x is the length of the shorter piece earlier on.

How do I graph y=-6/5x

kkurt [141]

-6/5 is the slope. you start at point (0,0) and then move down 6 units and to the right 5 units and then create one point. from that point, go down 6 units and to the right 5 units and repeat. when you reach the bottom of the graph stop. go back to (0,0) and then move up 6 units and to the left 5 units. connect the points with a ruler and add arrows to each side. label your line with "y=-6/5x" on the line

Prove that for all n in the naturals, n(n+1)(n+2) is divisible by 3

DerKrebs [107]

By induction:

It's true for $n=1$ , since $1\cdot2\cdot3$ clearly contains a factor of 3.

Suppose it's true for $n=k$ , that $k(k+1)(k+2)$ is divisible by 3. Then

$(k+1)(k+2)(k+3)=\dfrac{k(k+1)(k+2)(k+3)}k=\dfrac{3m(k+3)}k$

where $m$ is an integer. This reduces to

$\dfrac{3m(k+3)}k=3m+9\dfrac mk$

and both terms are clearly multiples of 3. We know that $\dfrac mk$ is an integer since we had set $m=k(k+1)(k+2)$ previously, which implies $m$ is a multiple of $k$ . So the statement is true.

Two sides of a triangle measure 9 cm and 23 cm. Which could be the measure of the third side of the triangle?

Verizon [17]

Hello,

Let's be x the length of the 3 side (9,x,23) ==>x>0

Using inequality triangular:

9<x+23==>x>9-23==>x>-14 (done)
x<9+23==>x<32
23<x+9==>x>14

SO 14<x<32
