Answer:

r=3, r=1, r= -1

Step-by-step explanation:

48r^3-144r^2-48r=-144

48r^3-144r^2-48r +144 =-144 + 144

48r^3-144r^2-48r+144=0

48(r-3)(r+1)(r-1)

r-3=0 r+1=0 r-1=0

r=3, r=1, r= -1

Prove that 6(n+6)-(2n+3) is odd number for all n£N​
Mice21 [21]

Answer:

\begin{aligned}6(n+6)-(2n+3) & = 6n+36-2n-3\\& = 4n+33\\& = 4n + 32 + 1\\& = 2(2n+16) + 1\end{aligned}

Any number multiplied by 2 is even, therefore 2(2n + 16) is even.

If 2(2n + 16) is even, then adding 1 to this makes it odd.

Thus proving that the given expression is an odd number for all n \in \mathbb{N}

 An art class is making a mural for their school which has a triangle drawn in the middle. The length of the bottom of the trian
Molodets [167]
<span>length of the bottom of the triangle = (y+4)
</span><span>Another side is 3 less than 2 times the length of the bottom of the triangle = 2(y+4)-3
</span><span>last side is 2 more than the bottom of the triangle = (y+4) + 2
perimeter of triangle = sum of all the sides of triangle
So, the expression for perimeter of this triangle is;
P = (y+4) + </span>2(y+4)-3 + (y+4)+2
Now, simplify this;
P= y+4+2y+8+y+4+2
P=4y+18
