Answer:

No solution 0≠3

Step-by-step explanation:

simplify parenthesis:

4x+4x+3=8x+6

combine like terms:

8x+3=8x+6

subtract three from both sides

8x=8x+3

subtract 8x from both sides

0≠3

This equation has no solution

i hope this helps u, pls give brainliest i only need one more then i level up and a thx, leave a comment if i am wrong

L = $20 r = 4% t = 2 years
Annette [7]
I'm guessing this is a question about interest rates? If you have $20 that increases by 4% in one year, you need to multiply 20 by 1.04. This gets you $20.8.

If you are talking about compound interest, we will take this number and multiply it again by 1.04 for the second year. 20.8 x 1.04 = $21.632. 

If it is instead simple interest, we will simply add another .8 dollars for each year, instead of getting 4% interest compounded every year onto the new value. This gets you $21.6.

Write a quadratic equation in standard form with the given roots
stich3 [128]

{x}^{2}  -  \frac{15x}{2}   +  \frac{7}{2}

Step-by-step explanation:

So we go backwards, since we have x= 1/2 , 7

(x -  \frac{1}{2} )(x - 7)

Now we have to foil to get the quadratic

{x}^{2}  - 7x -  \frac{1}{2} x +  \frac{7}{2}

We must simplify the terms

{x}^{2}  -  \frac{14x}{2}  -  \frac{x}{2}  +  \frac{7}{2}

Our final result comes out to be

{x}^{2}  -  \frac{15x}{2}   +  \frac{7}{2}

What is the height of cone S?
balu736 [363]

Answer:

12 cm

Step-by-step explanation:

First, we find the scale factor from cone S to cone T.

ratio of volumes = (vol of T)/(vol of S) = (6144 pi cm^3)/(768 pi cm^3) = 8

The ratio of the volumes is 8:1

The scale factor, which is the ratio of linear dimensions (height, radius, etc.), is the cubic root of the ratio of the volumes.

scale factor = cubic root of 8 = 2

The height of cube T is 24 cm, so the height of cube S is 24 cm/2 = 12 cm.
